Elevated Gamma GT and Cholesterol Levels on GLP-1 Therapy
After adhering to a GLP-1 regimen for four months, I recently had my blood drawn for testing. To my surprise, my gamma GT level has soared to 163, and my cholesterol has also risen to 6.2. During this period, I successfully shed 55 pounds (approximately 25 kilograms), which is fantastic news. However, I have no history of high cholesterol, making this development unexpected. Before starting Mounjaro, my gamma GT was already elevated at 65, likely due to my ongoing use of sulfasalazine at a dose of 2000 mg daily and regular consumption of around 1000 mg of Tylenol over several years. I anticipated that the tirzepatide would yield positive effects, so these alarming lab results have left me quite puzzled. While I am ecstatic about my weight loss progress, the prospect of having to discontinue this medication due to my elevated gamma GT levels is concerning. Thankfully, other liver function tests, including ALT, AST, and bilirubin, have remained within normal ranges.

Congratulations on your significant weight loss; that’s an impressive achievement! However, I understand that your recent lab results regarding elevated gamma GT and cholesterol levels can be concerning, especially as you are on GLP-1 therapy (Mounjaro).
Main Points:
- Elevated gamma GT and cholesterol can result from various factors, and your weight loss and medication regimen may be influencing these changes.
- Monitoring and managing these changes is important, especially considering your condition and medications.
Explanation: Gamma GT (GGT) is an enzyme that indicates liver function and can be elevated due to various reasons, including medication use, alcohol consumption, and liver inflammation. In your case, ongoing use of sulfasalazine and acetaminophen (Tylenol) could contribute to a higher GGT level. On the other hand, an increase in cholesterol levels is also not uncommon during weight loss, particularly if your diet has changed significantly.
Your other liver tests (ALT, AST, bilirubin) being normal is encouraging, suggesting your liver function remains stable despite the elevated GGT. It’s important to distinguish whether the changes in your blood work are due to the GLP-1 therapy or other factors related to your health history or lifestyle.
Next Steps:
-
Monitor Symptoms: Keep track of any symptoms you may experience such as fatigue, abdominal pain, or jaundice (yellowing of the skin or eyes). Note if any symptoms arise.
-
Evaluate Medication Use: Continue monitoring your use of sulfasalazine and Tylenol. If possible, discuss with your healthcare provider about the necessity of these medications and consider alternatives that may have less impact on your liver.
-
Dietary Considerations: Focus on a balanced diet, rich in fruits, vegetables, whole grains, and healthy fats, which can help manage cholesterol levels. Reducing saturated fat and added sugars may also be beneficial.
-
Follow-Up Testing: Keep regular follow-up appointments to monitor your GGT and cholesterol levels. It may be helpful to repeat the tests in a few months to see if there are any changes, especially with any lifestyle adjustments.
-
Lifestyle Modifications: Engage in regular physical activity, which can assist in managing cholesterol and improving overall health. Aim for at least 150 minutes of moderate exercise weekly.
If your concerns persist or if you notice any significant changes in your health, don’t hesitate to reach out for further medical advice. Keep celebrating your progress while taking these steps to ensure your health remains on track!

Understanding My Symptoms: A Personal Account
I’m sharing my experiences here, as I haven’t received much feedback elsewhere. I am a 15-year-old female, measuring about 5 feet tall (152 cm) and weighing between 105 and 110 pounds (47-50 kg). I identify as Hispanic and Cuban, and legally fall under the white classification. I reside in Palm Beach County, Florida, and I am a U.S. citizen. I have a diagnosis of Autism and previously had ADD, although that diagnosis has been dropped, which leaves me unsure about my current condition—whether ADHD applies or not. Additionally, I have a past history of anemia, although it is currently not diagnosed. For the past year, I've experienced a range of symptoms that appear intermittently and are often present almost daily. While these symptoms vary, they haven’t subsided. I’ve noticed that both physical activity and caffeine can either trigger or exacerbate these issues. Now, I’d like to detail the symptoms I've been facing. One of my major concerns is my balance; when I stand, I often feel unsteady, and sometimes I even limp. This particular symptom is quite troubling as it occurs frequently. I also experience occasional dizziness and fatigue, which leaves me feeling too weak to move, causing me to remain still for prolonged periods. During episodes of significant fatigue or balance issues, I find myself starting to stutter and I suspect my speech may slur at times. Additionally, my hands sometimes shake, especially when I struggle to walk. There could be other symptoms I haven’t recalled yet, but this is what I remember for now. I will provide updates if I think of anything else, and I welcome any engagement. Furthermore, I’ve noticed irregularities with my heart rate. Initially, when these symptoms began, my resting heart rate dropped from the 80s and 90s to the 50s and 60s; this lower rate has persisted. Lately, however, even simple tasks such as standing, walking short distances, or rocking back and forth (which I do as a self-soothing mechanism) have caused my heart rate to spike to the 100s. These changes are new, while the other symptoms have been consistent for about a year. I genuinely seek guidance or support, as I feel uneasy relying on AI for self-assessment. Unfortunately, I can't afford doctor visits at this time, and my caretaker has shown little concern for my well-being. Therefore, please refrain from suggesting medical consultations. Thank you for taking the time to read my story. I’m open to any questions.
Understanding Lymph Node Sensitivity
A 32-year-old female with a BMI of 28 poses a concern about potential lymph node activity. Over the past three months, she has noticed tender areas coinciding with her menstrual cycle. She has detected slight lumps, but is careful not to press deeply into the tissue to avoid further discomfort. Initially, in December, the sensitivity was localized to the left side of her breast. In January, she observed similar tenderness in her inner left thigh, and by February, both areas and the region above her armpit were affected. Additionally, she has been experiencing fluctuations in her hormonal balance lately. The discomfort in her left breast has persisted for most of this time since December. She wonders whether this is a typical response from lymph nodes due to hormonal changes or if it would be advisable to consult her general practitioner for further evaluation.
Seeking Guidance on Recurring Pilonidal Sinus Issues
I'm a 17-year-old male of Indian descent, standing at 5'8" and weighing 103 kilograms, and I'm dealing with pilonidal sinus problems. My issues began when I noticed blood on the toilet seat; I initially dismissed it as perhaps an anal fissure. However, after four months, I visited a doctor who diagnosed me with a pilonidal sinus. My symptoms included an unpleasant odor and bloody discharge that often stained my clothing. Subsequently, I was placed on a surgical waiting list. By the time my surgery arrived, the situation had worsened significantly, making the procedure even more traumatic and painful than anticipated. The surgeon ended up removing more tissue than originally planned. During my recovery, I inspected the surgical site and discovered a noticeable indentation at the top with various irregular bumps extending down. The doctor assured me that these would eventually fade, but instead, they collected lint and hair over time. Fast forward a year, and I began to notice the same familiar odor again, filling me with anxiety about a potential recurrence. Now, as an 11th grader, I am under pressure to maintain good grades and cannot afford to miss school. Presently, my symptoms include the telltale smell, although I haven’t observed any discharge or developed any additional openings aside from the dimple left from my previous surgery. Before the operation, the infected sinuses extended close to the rectum, which is why I am concerned that a new pilonidal sinus may have formed in the same area. At this moment, I am free from pain but cannot shake the anxiety surrounding the reappearance of the odor associated with this uncomfortable condition.
Concerned About My Toes' Health
At 27 years old, I’m feeling overwhelmed about my foot condition. For over a decade, since I was 16, I’ve dealt with recurring athlete's foot, primarily between my last two toes on both feet. Despite my efforts to manage this issue with various creams, sprays, powders, and even discarding all my footwear to start anew, the problem persists. Now, I suspect I might be experiencing a nail infection. All of my toenails are fragile and don’t trim easily, and they seem to grow in an unusual manner. Particularly troubling is my big toe on both feet, which appears to have several layers of nails; it seems as if the nails detach from the base and grow upwards rather than falling off, resulting in a stack of nails. While my feet are not foul-smelling and there’s no discharge, I do notice some swelling, and occasionally, I experience pain while walking; it comes and goes. Recently, I observed that the area where my athlete's foot initially developed is now taking on a greenish hue. This has left me feeling quite embarrassed. Despite trying multiple treatments for athlete's foot and toenails, nothing has provided relief. I even reached out to my doctor, only to be informed that they don’t handle cases of athlete's foot. I am at my wit's end and genuinely concerned about what might happen to my toes. I would greatly appreciate any advice from medical professionals regarding my situation.
