I want to get rid of big size of my stomach in the age of 25. Actually this size of my stomach is because of edema right from my childwood when I got attacked by kwahsiorkar. Will abdominal exercises produce some effect in reducing the size.

If you have edemas as the result of a medical condition, no.

What is a kwahsiorkar?

In general, the best way to get rid of a big stomach is to watch your diet, and reduce the sugar and white carbs.
