I have a lot of gas, my navel is leering smelly fluid sometimes and I have excessive hair fall like 5000 hair a day. ..like how cancer patients lose?

Hair loss/ navel d/c. Check thyroid studies. CBC, cortisol, iron, sed rate, CRP, ANA . May be gluten sensitivity,autoimmune disease or gallbladder , It is not usual to have a discharge from the navel, may be infection ,yeast , could try desitin (zinc oxide diaper cream) at the site and see if improves over next 2 days .Take a multivitamin a day .Need to follow up with doctor this week.
