Hi, Welcome to Health care magic forum.
The reason for such a huge tummy may be the fat accumulation,
liver enlargement, etc.
I advise you to consult a physician for diagnosis and treatment.
He may need to have an
ultrasound, for diagnosis of enlarged liver.
If fat is the only cause he can try to reduce it by 3 steps.
Keep the weight under control by by cutting the calories, sweets, and fatty foods.
Practice morning walk,
yoga, exercises, and keep on working some thing, like doing any work in front.
Minimize the sleeping time, practice late to bed and and early to rise.
Wishing for a quick and complete recovery. Thank you.
