Married fatigue, all over weak, a bit nauseous, thin, what's going on?

Patient's question:

No

Doctor's answer:

Hello, if you are underweight, it is important to first check for any potential underlying medical conditions. For example, digestive system disorders can easily lead to weight loss. Only after ruling out medical issues should you proceed with a weight gain plan. With sufficient protein intake, it is advisable to consume more foods rich in fats and carbohydrates (such as starch, sugars, etc.). This way, excess energy can be converted into fat and stored beneath the skin, helping underweight individuals to develop a healthier physique.
