Even when levothyroxine keeps your thyroid hormones in range, persistent digestive issues and insomnia can be linked to conditions like slow stomach emptying (gastroparesis), Irritable Bowel Syndrome (IBS), or gut flora imbalances. Sometimes, how your body absorbs the medication plays a role too. I highly recommend discussing these symptoms with a gastroenterologist to explore these possibilities.

Your elevated TSH of 10.70 mIU/L suggests your thyroid is still underactive, which directly slows digestion and worsens IBS-C symptoms. Since you recently increased your Thyronorm (levothyroxine) to 75 mcg, it can take 6 to 8 weeks for your TSH levels to stabilize and for your bowel habits to improve. Please continue taking your Lubowell (lubiprostone) as prescribed, ensure you take your thyroid medication on an empty stomach first thing in the morning, and follow up with your doctor in a few weeks to recheck your TSH levels to see if further adjustments are needed.

Your tiredness and headaches might suggest your Thyronorm (levothyroxine) dose needs checking, as thyroid imbalances can cause this. Nausea and burping can sometimes occur with vitamin supplements like Meconerve (vitamin B12) or Tayo 65 (vitamin D3), especially if taken on an empty stomach. Yes, it is best to temporarily stop your Meconerve and Tayo 65 supplements for about 10 to 14 days before your blood test to ensure accurate results. Please consult your doctor before making any changes to your thyroid medication.

For regular check-ups while taking Thyronorm (levothyroxine) 75 mcg daily, you should consult either an endocrinologist (a hormone specialist) or a general physician. Both can comfortably manage your routine monitoring. I suggest getting a fresh Thyroid Function Test (TSH, Free T3, Free T4) blood test done just before your visit so the doctor has the latest updates to review your dosage. Please continue taking your medication daily as prescribed.

Your muscle cramps and tingling around your lips and face could point to low calcium levels, which sometimes occurs alongside thyroid conditions. Additionally, hair loss, blood pressure changes, and a strange feeling in your head can be linked to fluctuations in your thyroid levels from Thyronorm (levothyroxine), or changes related to your history of seizures and past Zonisep (zonisamide) use. It is very important to have your thyroid and calcium levels checked by your doctor soon to safely get you feeling better.

A starting dose of 50 mcg of Thyronorm (levothyroxine) is a very standard and appropriate dose for a TSH level of 7.25, which indicates a mildly underactive thyroid. Regarding your cycle, thyroid hormones closely regulate menstruation. An underactive thyroid itself often causes irregular or missed periods. When starting levothyroxine, your body undergoes a temporary hormonal adjustment, which can sometimes delay your period. As your hormone levels stabilize over the next few weeks, your cycle should become regular. Please share these updates with your doctor to monitor your progress.
