How to improve gastrointestinal function?


Hello doctor, my gastrointestinal health is not very good.
Besides frequently having diarrhea, I also find it difficult to gain weight.
I previously visited Kaohsiung 802 Hospital for a thorough examination, and aside from an endoscopy, all tests were conducted, and the doctor said there were no issues.
Therefore, it is presumed that I simply have poor gastrointestinal function.
I am very thin; currently, I am 165 cm tall and weigh only 51 kg.
I am actively trying to gain weight, but the food I consume does not seem to reflect on my weight.
I believe poor gastrointestinal function is the main reason.
How can I improve my gastrointestinal function? I really want to weigh at least 54 kg, but it seems I lose weight faster than I can gain it.
Aside from a few meals where my weight briefly reached 52 kg, it generally stays between 50 and 51 kg.
Can you please advise me on how to improve my gastrointestinal function or suggest methods to gain weight? Thank you very much.

Hello Mr.
KK: As long as you maintain a balanced diet and increase your caloric and protein intake, there should be no issues with digestion and absorption.
The only concern is that you may experience loose stools due to poorly formed stools, which can be managed with medication.

Improving digestive health and effectively gaining weight can be a challenging journey, especially when dealing with gastrointestinal issues. Based on your situation, it seems that you have already undergone thorough medical examinations, and the results indicated no significant underlying health problems. This suggests that your digestive system may simply be functioning suboptimally, which can affect your ability to gain weight. Here are some strategies to help improve your digestive health and facilitate healthy weight gain.


1. Focus on Nutrient-Dense Foods
To gain weight effectively, it’s crucial to consume foods that are high in calories but also rich in nutrients. Here are some food groups to consider:
- Healthy Fats: Incorporate sources of healthy fats such as avocados, nuts, seeds, and olive oil. These foods are calorie-dense and can help you increase your caloric intake without having to eat large volumes of food.

- Protein-Rich Foods: Include lean meats, fish, eggs, dairy products, legumes, and plant-based proteins. Protein is essential for muscle growth and repair, which is particularly important if you are trying to gain weight.

- Whole Grains: Opt for whole grains like brown rice, quinoa, oats, and whole-grain bread. These provide not only calories but also fiber, which is beneficial for digestive health.

- Fruits and Vegetables: While they are generally lower in calories, they are essential for providing vitamins, minerals, and fiber. Choose starchy vegetables like potatoes and corn, which can help increase your caloric intake.


2. Eat Smaller, More Frequent Meals
Instead of three large meals, try eating five to six smaller meals throughout the day. This can help you consume more calories without overwhelming your digestive system. Make sure each meal includes a balance of carbohydrates, proteins, and fats.


3. Stay Hydrated, but Wisely
While hydration is important, drinking large amounts of water before or during meals can fill you up and reduce your appetite. Instead, try to drink fluids between meals. Consider smoothies or shakes that combine fruits, vegetables, protein powder, and healthy fats, as they can be nutritious and calorie-dense.


4. Incorporate Digestive Aids
To improve your digestive health, consider the following:
- Probiotics: These beneficial bacteria can help improve gut health. You can find probiotics in yogurt, kefir, sauerkraut, and supplements.

- Digestive Enzymes: These can help break down food more effectively, making it easier for your body to absorb nutrients. Consult with a healthcare professional before starting any supplements.

- Fiber: While fiber is essential for digestive health, too much can cause bloating and discomfort. Gradually increase your fiber intake and focus on soluble fiber sources like oats, beans, and fruits.


5. Monitor Your Stress Levels
Stress can significantly impact digestive health and appetite. Engage in stress-reducing activities such as yoga, meditation, or deep-breathing exercises. Regular physical activity can also help alleviate stress and improve overall well-being.


6. Consult a Nutritionist or Dietitian
Given your specific concerns and goals, working with a registered dietitian or nutritionist can provide personalized guidance. They can help you create a tailored meal plan that aligns with your weight gain goals while considering your digestive health.


7. Be Patient and Consistent
Gaining weight, especially in a healthy manner, takes time and consistency. Monitor your progress and adjust your strategies as needed. It’s important to focus on gradual weight gain rather than rapid changes, which can be unhealthy.

In conclusion, improving your digestive health and gaining weight effectively involves a combination of dietary adjustments, lifestyle changes, and possibly professional guidance. By focusing on nutrient-dense foods, eating smaller meals more frequently, and incorporating digestive aids, you can create a supportive environment for your body to gain weight healthily. Remember to be patient with yourself throughout this process, as sustainable changes take time.
