Thank you for providing such a detailed history. Based on the information you’ve shared, several factors may be contributing to your symptoms. Your
HbA1c of 5.8% suggests prediabetes and possible insulin resistance, although this alone may not fully explain difficulty losing weight. A
TSH of 5.7 mIU/L with normal T3/T4 is consistent with subclinical hypothyroidism, which may contribute to constipation and mild metabolic slowing in some individuals, but treatment depends on repeat
thyroid tests, symptoms, and thyroid antibody status. Iron deficiency can also cause fatigue and reduce exercise tolerance, so it should be corrected.
Your BMI is approximately 23.8 kg/m², which is within the normal range. Therefore, medical weight-loss medications are generally not recommended unless there are specific obesity-related indications. Since your weight is only mildly above your desired target, lifestyle optimization remains the safest and most effective approach.
Given your long-standing constipation, bloating, and incomplete evacuation, I would recommend evaluation for chronic constipation causes, including serum
ferritin,
vitamin B12,
vitamin D, fasting insulin (or HOMA-IR if indicated), anti-TPO antibodies, repeat TSH after 6–8 weeks, and screening for celiac disease (tTG-IgA with total IgA). If symptoms persist, a gastroenterology evaluation for pelvic floor dysfunction or slow-transit constipation may be appropriate.
Management should focus on correcting iron deficiency, optimizing thyroid status if indicated, ensuring adequate hydration, gradually increasing soluble fiber, regular physical activity, and using evidence-based constipation treatment (such as polyethylene glycol or other agents if prescribed). A low-FODMAP diet trial may also help if bloating
