Dear user ,
thank you for reaching out for an advice . well being overweight
is not a good idea. reducing your weight will always help you feel lighter and better. for your stomach problem you have to check with your GP for the following issues :
2. celiac disease
3. lactose intolerance
4.IBS (irritable bowel syndrome
for the sympotms you mentioned with history of thyroid and the fact you feel non energetic you probably could have developed some vitamin deficiencies such as Vit D .
anyhow raise the suggestions i have mentioned to your GP and discuss your concerned with him or her.
if you find the answer helpful please rate it .
