Higher Insulin Resistance… After Weight Loss?

22 replies8 peopleMay 30, 2026☆ Follow
Summary

Why would bloodwork show signs of higher insulin resistance or hyperinsulinemia after major weight loss on GLP-1 drugs, along with hypoglycemia symptoms?

The original poster reports dizziness, vision issues, low fasting glucose readings, and bloodwork after losing substantial weight on tirzepatide. Participants conclude the pattern reflects heightened insulin sensitivity or lingering hyperinsulinemia rather than worsening resistance, triggered by rapid body changes and possible glucagon shifts. Advice centers on lowering doses, adding complex carbs or muscle work, and using a CGM for monitoring. Most view the low HbA1c and post-meal glucose drops as positive signs overall.

What this discussion establishesWhere people disagree

Whether the situation is best described as hyperinsulinemia, temporary hypersensitivity, or glucose dysregulation, and how quickly to switch or taper specific peptides.

Still open

How long the imbalance may last after weight stabilizes and whether inflammation or beta-cell lag is the main driver.

Nothing here is advice.

So here’s a weird one… I followed the usual advice, got extensive bloodwork before starting peptides, and just finished another round after several months on them. I play a lot of golf and focus workouts on club speed. During one round on a mild day while hydrated I suddenly got dizzy, then vision narrowed with rushing sounds in my ears. I had to stop for 45 minutes, drank fluids and ate jerky, but symptoms returned when I tried again. Heart tests and electrolyte checks came back normal, yet the dizzy spells hit two or three times a week. New issues include sleep paralysis after night terrors a few nights a month. My doctor wouldn’t order the peptide-related labs I wanted, so I ordered them myself. Results are coming in and most numbers look better: total cholesterol dropped 22 points and LDL fell 19. Triglycerides went from 113 to

I'm dealing with this now. The challenge comes down to choosing between a regular doctor covered by my plan who might prescribe what I want, or paying directly where it's hit or miss on getting the right order. Plus their online pages try to promote different options that they will supply easily. I'm wondering about the right things to search when looking around.

I found that fine tuning everything too much isn't helpful. My long term sugar control came back solid. Glucose after meals falls quick enough on its own. The main issue for me involves low sugar moments that might stop me waking up someday. So i reduced those glp amounts slightly and kept just one. That mots compound helps plenty yet makes the lows hit harder. Three times last month i ran into trouble mixing it with the rest. Adding slower digesting carbs that avoid jumps has worked into my meals. A constant tracker gives me early warnings before levels get dangerous.

Think about this situation differently. The physician's actual duty centers on sharing knowledge from their training, responding to concerns, outlining downsides tied to various paths, and offering backup once choices get made. Their position does not involve issuing orders, demanding compliance, or criticizing when plans diverge. I reject that approach from any physician, and most avoid attempting it once expectations get stated plainly.

My physician pushed cholesterol drugs along with ending tobacco use during recent visits. I felt unprepared for either step. I described plans to begin a weight-control injection first, bring weight down, and revisit everything afterward. The physician doubted even that combined with quitting would shift numbers enough. I accepted the view and chose to move ahead anyway, checking results after several months. Should weight reach a healthy range yet cholesterol stay elevated, discussion of next steps could follow, though not both changes together. The physician described the current odds of a heart problem. I expressed thanks for the details. We ended the visit aligned as partners.

During the upcoming check-in, if cholesterol remains high I plan to hold off on drugs. Tobacco cessation starts early next month. Time will pass after that before levels get tested again. Should they still sit above target, drugs enter consideration then. The heart risk level right now stays clear because the physician laid it out, which matches the service coverage provides. The physician lacks any command over my actions, regardless of any impression otherwise. Yours holds the same limited role. Opposition to the injections counts as acceptable input with reasons attached, yet the choice stands and requires continued professional support in return. A polite insistence on that support remains reasonable.

How did your inflammation levels turn out? Was cytokines part of the panel? Following my quick drop of sixty pounds, blood tests showed inflammation as the primary concern. My blood sugar registered around one hundred. Several artificial intelligence systems indicated the bodily strain from fast slimming probably triggered it. They mentioned that swelling might temporarily lead to reduced insulin sensitivity. Those systems recommended checking once my mass leveled off. I entered my background details like ethnicity, sex, initial and final mass, any prescriptions, and the period of my slimming into an AI tool such as ChatGPT before providing my lab outcomes.

Apologizing for dumping this lengthy response from an ai tool but it came from a version set to academic research with added instructions so the output should hold up well and it even rates how sure it is about each point. I felt puzzled since nothing seemed to back up the claim of worse insulin resistance so i pasted the text and queried it directly. It suggests a few reasons why the numbers and feelings might line up this way. Splitting it into two sections because of the length. The ai response i share the doubt. Nothing in the original text seems to prove insulin resistance got worse and several numbers actually point the other way. The main problem is that the resistance calculation is being read without proper background and maybe outside its valid range. The model uses fasting glucose and insulin levels to estimate resistance through a more advanced formula that tries to reflect real body responses better than the basic version. In simple terms it flags higher insulin at the same glucose level as greater resistance yet it remains an indirect and imprecise stand-in rather than a true test. The on this description is strong. The numbers given inside the post do not line up with each other. The person lists clear drops in average glucose readings and big weight reduction along with better blood fat levels yet also reports a high resistance score. Taken together the improvements in those other markers normally suggest better sensitivity and overall metabolic health instead of any decline. The on that reading sits at medium to high. What stands out as strange is the insulin level paired with quite low glucose. Such a mix does not fit the usual pattern and opens several possible causes. The most common one is probably that the blood draw did not happen after a true overnight fast. These medications slow stomach emptying so nutrient absorption can stretch out and throw off timing assumptions even if someone believes they waited long enough. That mismatch could easily produce an insulin reading that looks elevated without reflecting real fasting conditions. This explanation feels like the strongest one at the moment.

The next part covers excess insulin production trailing the drop in body mass. That notion shows up a lot in discussions but feels overstated. Beta cells might keep releasing too much hormone even after sensitivity gets better, and there is some biological basis for secretion patterns taking time to catch up. Still a single HOMA reading from one moment does not establish it, and the very low blood sugar makes the number hard to read. I put in that low to medium.

Another angle involves an overshoot from gut hormones after meals. Those medications can boost insulin output sharply when food arrives. With any leftover nutrient uptake from slower stomach emptying, insulin could sit higher while glucose stays low, especially if the timing of the draw is off. The home readings listed do not point to resistance at all. They look more like tight control that might even dip too far at times. Again low to medium .

Lab error or odd result remains possible too. The fructosamine sitting below the usual range is worth noting and could come from unusually low average sugar, changes in how proteins turn over, or problems with the test itself. That marker covers only the past couple weeks and gets less use now that other measures took over.

HOMA calculations assume steady fasting conditions, yet the situation here includes big recent mass reduction, multiple gut hormone drugs, slowed emptying, low sugar, and possible rebound patterns. Those break the steady state the model needs, so an out of range value might just reflect applying it where it does not fit well.

A drop in average sugar over months does not automatically prove better sensitivity on its own, since other factors like more hormone release, less carb intake, or the mass loss itself can lower it. In this setting though the combination of substantial mass reduction, better lipids, lower fasting sugar, much less sweet stuff, and the medications makes it likely sensitivity did improve a fair amount. The idea that resistance got markedly worse does not hold up from what is shown.

What stands out most are the repeated dizzy spells and narrowed vision. Those plus the rushing sound during activity and a reading of 52 point more toward low sugar effects, pressure changes, fluid shifts, or nerve responses than to resistance. The mix of the drugs, big mass loss, lower food, and long gaps without eating could easily produce that. The drink and snack mentioned add some salt and protein but little quick energy. Activity plus restricted calories plus the medications plus extended fasts lines up with feeling off. Not a firm call, just the part that seems most obvious.

Overall the numbers do not make a strong case for resistance getting worse. They fit better with much tighter sugar control plus one odd fasting insulin that could stem from when it was taken, leftover after meal effects, or the model not applying cleanly. A lone calculated value deserves caution when someone is on several of these agents after losing a lot of weight recently. The whole picture suggests resistance has actually gotten better, and any mismatched results might sort out with later checks. The dizzy episodes seem more tied to pressure, fluid, or salts than anything else.

In the diabetes facility where I work I've come across cases like this. It looks like the reverse of resistance to insulin with an overreaction instead plus erratic blood sugar handling. Your lower readings point that way. From memory the issues described line up more with low blood sugar than the other direction. Major body mass reduction might have set it off as an abrupt jolt to everything. Glucagon's impact also throws hormone balance off quite sharply. Hormone signals probably need time to settle back down. I've kept powdered sugar nearby for any sudden dips. The long term blood sugar reading is the key one and it came out great. I wouldn't go for that peptide right now. Lifting weights could shift things by turning sugar into stored form and lowering insulin output.

The question stands out as a good one. Before this compound I dealt with joint inflammation for three years and only got partial relief from another prescription. The current regimen plus one more item cut back how much of the earlier drug I needed. Skin symptoms stayed light while the joints took the bigger hit in a matching pattern across both sides including the first three digits of each hand plus wrists neck and ankles. That layout probably traces back to fifteen seasons of structured baseball plus later rounds of golf. On the bloodwork side rheumatoid factor sat at eleven high sensitivity c reactive protein fell to two point eight from a prior peak above seven and fibrinogen landed just above range at four hundred twenty three. Cytokine numbers are still missing. I ordered broad panels from a testing service and tacked on extras such as testosterone and igf one. Feeding personal details into an ai produced similar output though I used a different model. Checking with the main alternatives might yield other suggestions. More reading makes me think the ai pointed to excess insulin output instead of resistance. My system handles the insulin it makes without issue yet releases a flood after even one carb. Dropping sixty pounds counts as a major achievement.

Upon further reflection I agree with what you said. My current dose appears to be working fine so there's no reason to increase it. Instead of reacting to an automated warning I thought it through on my own and now suspect excessive insulin output rather than poor cell response. That explanation fits the pattern better since my body releases plenty of the hormone to bring glucose down yet still makes far more than required. Does that conclusion hold up?

Honestly I'm uncertain whether this elevated insulin state counts as sudden or possibly ongoing. The weight drop of around twenty five kilograms suggests there was excess body mass beforehand which commonly triggers some glucose handling problems. With my own condition the improvement in handling after shedding pounds shows up first in the outer tissues and only later inside the organs. In this situation it seems like a passing phase of too much insulin alongside very low blood sugar. Since no outside insulin is involved and readings sit below normal this points to unusually strong response yet the system keeps pumping out excess amounts anyway which looks like a mismatch in regulation. So the idea would be finding ways to dial back that output through lower carb eating periods without food or meals heavy in protein though sticking with those long term might prove tricky. Adding muscle could let any extra sugar get stored there instead of turning into fat which is what the hormone normally promotes. If the goal is just storing it as glycogen then maybe less of that hormone is required at all. The other medication could be making things worse as well since cutting back on meals already keeps sugar low while insulin stays high so those factors build on each other. Getting into lifting earlier might help address it.

I'm with you on that. My schedule matches up nicely since I'm leaving the country soon for roughly fourteen days. I'll have just Tirz along for the trip. Up until I hit my first target weight, I'm dividing the Tirz shots with the bigger one on Friday and a smaller add-on on Tuesday. After reaching that point, I'll move slowly across to Reta by itself to shed the last ten or twelve pounds at a relaxed pace while putting more focus on building muscle. On the training side, I've been doing golf club swing speed work. It delivers a solid power session along with some cardio effect. My average tee ball speed rose from 132 mph to 141 mph. That gave me around fifteen extra yards on carry, and my typical drive distance is up by twenty-two yards from the prior year end. The routine has helped, at least until the shots after that, haha.

Perhaps I'm off base, but this looks like it focuses on power instead of strength. Rather than the overall force produced, it appears to emphasize the peak force created in a short period. I engage in a little mixed martial arts, pulling contests, and hand gripping exercises, and it seems a lot like the explosive drills in my pulling and hitting workout routines.

I've come across plenty of techniques. Much of this centers on developing quick-response muscle groups, of which I apparently possess none. One involves using reduced loads for leg bends that include leaping slightly from the surface. Another uses a comparable apparatus for arm extensions, yet with cords attached, positioning in a rearward motion with complete extension, then switching between quick motions under less resistance and deliberate ones under more. Wielding heavy sticks works too, or exercises with twelve spheres positioned close together where I advance to strike at full power, prioritizing velocity over aim. Right after the strike I move ahead and repeat the powerful hit, reaching twelve maximum efforts within sixty seconds. Surprisingly the areas becoming most tender turn out to be the back of my thighs, front of my thighs, and side abdominals, rarely the limbs which one might expect to suffer most.

Yeah this amounts to explosive strength work also called plyometrics.

My blood sugar monitor should show up before long. I've been pricking my finger for checks while waiting because the package vanished last weekend. That's frustrating. A couple of mornings it read really low under fifty. The other results came in at sixty eight and seventy one. This device ought to show me the pace of my glucose shifts more clearly. I believe some kind of exam lasting two hours can follow those changes but I don't recall its name. That option is no longer in the running and I appreciate the guidance. I'm putting off the next one for now. I'll wait until reaching my target weight before pushing hard toward strength gains to whatever degree an unfit geek like me can manage and also taper down my current dose further. I'll cut back by another amount with the following injection.

Guess that proves how little I understood back then. Truthfully, I didn't put enough effort into staying fit. My body stayed capable for daily tasks, yet I paid no attention to exercise. Now I feel sorry about that, especially since I'm aging and the natural power I once had is fading away.

BlueMarble65archiveJun 1

I deal with episodes where my blood sugar falls too low. Spreading out several modest meals evenly makes a big difference compared to having supper early and then going without food until late the following morning. Cutting back on the glp-1 medication helps too since that strength is insufficient.

It's really my own problem here. I'm extremely submissive and even now, despite how old I am, I link specific jobs and traits to power. For example, imagining there's no other physician available or anything extreme like that. To be truthful, part of the reason involves the prescriptions I receive. Those scripts took a lot of effort to obtain initially, and plenty of physicians seem to be backing away from issuing them these days, or forcing me to go through all those steps repeatedly. Still, you're correct. I should just toughen up and switch physicians. After all, my healthcare expenses are already high enough.

Everyone starts out at some point in their training journey. What matters most is taking that first step forward. Starting later is preferable to not starting at all. Regarding the soreness in the arms compared to other areas feeling the strain, the reason is probably straightforward. The arms had more strength built up than the rest for that specific kind of work. This happens quite often. Our bodies are signaling which areas require more attention and growth. Almost all powerful actions originate in the lower body and core due to the need to overcome resistance from gravity and momentum.

Actually my point was the other way around at first. You might not have to switch physicians. You could tell yours you get their view but are going ahead anyway and want to discuss something else that still puzzles you. Yet after checking the message again I noticed these were peptides outside the GLP-1 group. That shifted my view a lot. No way would I mention taking them to my doctor. It'd end up in the file and give the insurance a way to hassle me later.

GreenQuill96archiveJun 2

Yeah, that checks out. Somehow I'm dealing with my third trainee doctor now and about to get a fourth. These folks finish their stint handling basic health issues then move along. I'd prefer at least one who recognizes me personally.
