How to improve poor gastrointestinal absorption?


Hello, I am a male who has always been very thin and has difficulty gaining weight unless I eat a lot, like six or seven bowls of rice in one meal.
My face is severely thin and sunken, and my friends say it might be due to poor gastrointestinal absorption, possibly only absorbing about 20% of the nutrients I consume.
I am currently 169 cm tall and weigh less than 45 kg.
What dietary changes can I make to improve this? Additionally, I often feel a lack of appetite and struggle to eat; what should I consume during those times? Thank you.

Hello! Based on your height of 169 cm, your ideal weight range is between 56 to 69 kg.
However, at only 45 kg, you are indeed underweight.
It is recommended that you consult a gastroenterologist to check for any gastrointestinal issues.
If there are none, you may want to see an endocrinologist to rule out hyperthyroidism.
If both evaluations are normal, consider adopting a strategy of eating smaller, more frequent meals and incorporating high-calorie foods to gradually increase your weight.
However, if there are any underlying health issues, please address those first, as treating the condition can help you gain weight naturally.
Wishing you success in gaining weight!

Maintaining or increasing weight, especially for individuals who are underweight, can be a challenging endeavor. It requires a strategic approach to diet and lifestyle that focuses on enhancing nutrient absorption and ensuring adequate caloric intake. Here are some dietary tips and recommendations that can help improve your situation.


Understanding Nutrient Absorption
First, it's essential to understand that nutrient absorption can be influenced by various factors, including the health of your gastrointestinal tract, the types of foods you consume, and your overall dietary habits. If you suspect that your body is not absorbing nutrients effectively, it may be beneficial to consult with a healthcare professional or a registered dietitian who can assess your specific situation and recommend appropriate interventions.


Dietary Tips for Weight Gain
1. Increase Caloric Intake Gradually: Instead of trying to consume large quantities of food at once, aim to increase your caloric intake gradually. This can be achieved by adding small, nutrient-dense snacks between meals. Foods like nuts, seeds, avocados, and nut butters are high in calories and healthy fats, making them excellent choices for weight gain.

2. Focus on Nutrient-Dense Foods: Choose foods that are high in calories but also provide essential nutrients. Examples include:
- Healthy Fats: Incorporate sources of healthy fats such as olive oil, coconut oil, avocados, and fatty fish (like salmon and mackerel).

- Protein-Rich Foods: Include lean meats, poultry, fish, eggs, dairy products, legumes, and plant-based protein sources like tofu and tempeh. Protein is crucial for muscle building and repair, which can help improve your overall body composition.

- Whole Grains: Opt for whole grains like brown rice, quinoa, oats, and whole-grain bread, which provide complex carbohydrates and fiber.

3. Eat More Frequently: If you struggle with a lack of appetite, try to eat smaller meals more frequently throughout the day. This can help you consume more calories without feeling overwhelmed. Aim for five to six smaller meals instead of three large ones.

4. Enhance Flavor and Appeal: Sometimes, a lack of appetite can be due to unappealing food. Experiment with different cooking methods, spices, and herbs to make your meals more enjoyable. Adding sauces or dressings can also enhance the flavor and caloric content of your meals.

5. Stay Hydrated but Avoid Filling Up on Fluids: While staying hydrated is important, drinking large amounts of fluids before or during meals can reduce your appetite. Try to drink fluids between meals instead.

6. Consider Nutritional Supplements: If you're finding it particularly challenging to meet your caloric needs through food alone, consider using nutritional supplements such as protein shakes or meal replacement drinks. These can provide concentrated sources of calories and nutrients.


Addressing Lack of Appetite
When you experience a lack of appetite, it can be helpful to:
- Eat Small Portions: Start with small portions of your favorite foods to avoid feeling overwhelmed.

- Choose High-Calorie Snacks: Keep high-calorie snacks on hand, such as trail mix, granola bars, or cheese, which can be consumed easily without much preparation.

- Incorporate Smoothies: Smoothies can be a great way to pack in calories and nutrients without requiring a large volume of food. Blend fruits, vegetables, yogurt, and nut butter for a nutritious drink.


Monitor Your Progress
Keep track of your weight and dietary intake to monitor your progress. If you find that you are still struggling to gain weight despite making these changes, it may be beneficial to seek further evaluation from a healthcare professional. They can help identify any underlying issues that may be affecting your ability to gain weight, such as gastrointestinal disorders or metabolic conditions.


Conclusion
Improving nutrient absorption and increasing weight is a gradual process that requires patience and consistency. By focusing on nutrient-dense foods, increasing caloric intake, and addressing any appetite issues, you can work towards achieving a healthier weight. Remember, it's essential to consult with a healthcare provider or a registered dietitian for personalized advice tailored to your specific needs.
