Suggest treatment for nausea,low potassium levels and TSH of 0.007

I m an 18 year old girl that was just diagnosed with hyperthyroidism about a month ago. I was experiencing nausea, insomnia, weight loss, high heart rate, and dizziness. My lab tests showed that my TSH was 0.007. Three weeks ago, I was put on 10mg of methimazole once a day, and 12.5 mg metoprolol twice a day. 3 days later, I was taken in an ambulance for dehydration and low potassium levels. Over the following two weeks, I slowly began to regain my appetite, and resumed my life as usual. However, two days ago I began feeling nauseous all of the time again, and had to be taken in an ambulance. After waiting in the ER for 2 hours, I left AMA. Last night I was again taken to the ER in an ambulance, but this time with shortness of breath. They found that my potassium levels were low again, and that so was my iron, though I believe that to be credited entirely to my Thalassemia Minor. Today, I am again feeling nauseous, even though I took a potassium supplement and some meclizine that the ER doctor recommended. What can I do, so that this nausea and disease don t take force me to leave college and return home? And, is this extreme nausea common?

Most of your symptoms (insomnia, weight loss, high heart rate, dizziness, and even nausea) can be attributed to Hyperthyroidism.

The treatment with Methimazole and the beta-blocker will ease the symptoms within a couple of weeks.

About Hypokalemia, I can say that this condition usually results from vomiting, diarrhea, adrenal gland disorders, or use of diuretics.

In rare cases, it can occur because someone is not getting enough potassium, in his diet.

In your case, the real cause of Hypokalemia is not clear, for this reason, the potassium supplement is very important.

Digestive problems and nausea can be related to your low potassium.

Extreme nausea in a young girl with hyperthyroidism is not common.

For this reason, in my opinion, all you can do is to continue with potassium supplement for some days and to take foods that are high in potassium like bananas, oranges, cantaloupe, apricots, and grapefruit.

You must stay under medical assistance because hypokalemia can be dangerous.

Other tips that can be helpful for you nausea are: Drink clear or ice-cold drinks, eat slowly and eat smaller, more frequent meals, Avoid fried, greasy, or sweet foods.

Hope I have answered your query. Let me know if I can assist you further.

Take care
