Welcome to HealthcareMagic,
It is normal for
umbilicus to get stretched out when the belly gets swollen. This is commonly seen in
obese individuals. As you husband is obese, I recommend him to follow my given below advise.
1. Regular exercise such as brisk walking for at least 30 minutes per day
2. Consume a diet rich in fruits, vegetables and low fat dairy products.
3. Have more of legumes and beans
4. Reduce salt intake to less than 5 grams per day (1 teaspoon is approximately 5 grams)
5. Limit biscuits, cakes, pastries, pies, processed meats, commercial burgers, pizza, fried foods, potato chips, crisps and other savoury snacks.
6. Avoid consuming alcohol and aerated drinks as they have high calories.
Hope that answers you question.
Regards, Dr.Imaad
