Hi there I understand your concern...be in a regular fallow up with your physician for
thyroid issues these symptoms may be due to your thyroid issues...thyronorm takes some time to show its response...Drink plenty of fluids, such as water or juice. This will help dilute mucous secretions and promote drainage. Avoid beverages that contain caffeine or alcohol, as they can be dehydrating. Drinking alcohol can also worsen the swelling of the lining of the sinuses and nose.
Moisten your sinus cavities. Drape a towel over your head as you breathe in the vapor from a bowl of hot water... Avoid foods that irritate your stomach, especially those that are spicy, acidic, fried or fatty... avoid coffee,tea etc... Avoid Stress as it may make your gastritis symptoms worse...Regards.
