For your weight of 56 kg and a TSH of 11 mIU/L, a common starting dose of levothyroxine (Thyronorm) is usually between 25 to 50 micrograms daily. Because everyone's body is unique, your doctor will tailor this dose specifically for you and likely recheck your TSH levels in 6 to 8 weeks to ensure it is perfect. For the best results, remember to take it on an empty stomach in the morning.

The i-pill (levonorgestrel) contains a high dose of hormones which can cause temporary fluid retention and bloating, mimicking rapid weight gain. This is temporary and typically resolves within a few days. While you are taking Thyronorm (levothyroxine) for your thyroid, a single dose of the emergency contraceptive will not cause permanent weight gain or disrupt your thyroid function long-term. If you continue to experience weight changes or feel unwell, it is a good idea to have your thyroid levels checked by your doctor to ensure your dosage is still correct.

It is very common to see normal T3 and T4 levels while TSH remains high. Your TSH of 9.433 suggests your body is asking for a bit more thyroid hormone than your current Thyronorm 75 (levothyroxine) dose is providing. Please do not worry, as this is a very manageable situation. However, please do not adjust your dose on your own. I highly recommend sharing these results with your doctor. They will likely need to slightly increase your levothyroxine dosage to help bring your TSH back into the optimal range and keep you feeling your best.

Since you manage depression and take Thyronorm, the safest approach is combination counseling and nicotine replacement therapy, like patches or lozenges. Some prescription options like generic bupropion can help both depression and quitting, but require a doctor's evaluation. Quitting smoking can sometimes affect thyroid medication absorption, so your doctor should monitor your thyroid levels. Together, you can create a gentle plan that supports your mood, manages weight, and addresses hair loss.

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.

A TSH level of 8.6 indicates a mildly underactive thyroid. The precise dose of Thyronorm (levothyroxine) must be tailored specifically to you by your doctor, who will consider your weight, symptoms, and complete blood work. Please consult them before starting any dosage. To help with hair loss in the meantime, focusing on a nutrient-rich diet with adequate iron and vitamin D can support hair regrowth as your thyroid levels stabilize.
