Yes, a severe vitamin D deficiency can absolutely cause chronic, dry, and bleeding cracked lips. Vitamin D (cholecalciferol) is essential for maintaining a healthy skin barrier and promoting skin healing. While your thyroid medication, Thyronorm, and allergy treatments manage those specific conditions, they cannot correct a deep nutrient deficiency. Addressing the root cause with Vitamin D3 is why you are finally seeing this wonderful improvement. Continue working with your doctor to monitor your levels, but this is a very reassuring sign that your skin is healing.

Since you have been taking Thyronorm (levothyroxine) 50 mcg for three years, these symptoms suggest your thyroid hormone levels may need to be re-evaluated. I gently recommend consulting your doctor to check your thyroid levels through a simple blood test. Often, a small adjustment to your levothyroxine dose can safely and effectively resolve these symptoms. Please be reassured that this is a very common experience and highly manageable once your levels are checked.

Please seek immediate medical care. Your TSH of 16.7 and symptoms like confusion require urgent evaluation by a doctor. It is also very important to have your skin redness checked. Please do not adjust your levothyroxine (Thyronorm) dose on your own, as doubling it to 200 mcg can be unsafe. A doctor will safely adjust your medication and find the cause of your symptoms. Get evaluated quickly.

Hypothyroidism usually requires lifelong thyroid hormone replacement (levothyroxine) because the thyroid gland cannot produce enough hormone on its own. While Ayurvedic remedies can support metabolism and overall well-being, there is no clinical evidence that they can completely cure hypothyroidism or safely replace your daily medication. Abruptly stopping your daily hormone pill can lead to complications like extreme fatigue, weight gain, and joint pain. You can use Ayurvedic therapies as a supportive treatment, but please do so alongside your current prescription and under the joint guidance of an endocrinologist and a qualified Ayurvedic doctor. Never alter your hormone dosage without checking your blood levels.

A negative Anti-TPO test is reassuring news, as it suggests your thyroid issue is likely not caused by an autoimmune condition. However, your rising TSH (from 5.54 to 6.68) indicates your thyroid is still struggling a bit, even on a low dose of Thyronorm (levothyroxine). Stopping your medication can cause your TSH to rise further over time, even if you feel well right now. I gently encourage you to discuss these results with your doctor to safely plan the next steps for your health.

Your TSH level of 3.45 mIU/L is within the normal target range (typically 0.4 to 4.5 mIU/L) for adults on levothyroxine (Thyronorm). This indicates your current 88 mcg dose is working well, and will likely be maintained. However, because target ranges can sometimes be tighter depending on your symptoms or if you are planning a pregnancy, consult your doctor.
