My Friend is suffering from constant heaviness and cramping in stomach from few days. He is around 26. He is living far from his home so he has no choice other than eating food outside and he was complaining that the food was very spicy. He also has a 3mm stone in his
kidney and taking medicine for that. He has lost around 3 kg weight and couldn't eat much because of the heaviness in stomach and is basically surviving on Fruits and some dairy products other than milk from few days. Please suggest a solution for the problem.
