Unable to gain weight?


Hello, doctor.
I've had trouble gaining weight since I was young, and my weight has remained unchanged until now, which bothers me a lot.
My stools are often loose and unformed, and I frequently experience gas.
However, I really want to gain weight.
What should I do?

Hello: Long-term unformed stools will not lead to fecal impaction or constipation.
If there are multiple occurrences, you may consider using medications for irritable bowel syndrome.
Health is the most important thing; being overweight is not necessary.
If you suspect a metabolic issue, you can consult a specialist in metabolism.
Changhua Hospital cares about your health.

More Info


Struggling to gain weight can be a frustrating experience, especially when it feels like no matter how much you eat, your weight remains unchanged. Based on your description, it seems that you are experiencing gastrointestinal issues, including loose stools and excessive gas, which could be contributing to your difficulty in gaining weight.
First, it’s important to understand that weight gain is fundamentally about consuming more calories than you expend. However, if you are experiencing gastrointestinal symptoms like diarrhea and bloating, this could indicate an underlying issue that needs to be addressed before you can effectively gain weight.


Possible Causes of Your Symptoms
1. Malabsorption: Conditions such as celiac disease, Crohn's disease, or other malabsorption syndromes can prevent your body from absorbing nutrients effectively. This can lead to weight loss or difficulty gaining weight, along with symptoms like diarrhea and gas.

2. Irritable Bowel Syndrome (IBS): IBS is a functional gastrointestinal disorder that can cause symptoms like bloating, gas, and irregular bowel movements. Stress and dietary choices can exacerbate these symptoms, making it difficult to maintain a healthy weight.

3. Dietary Factors: If your diet is low in calories or lacks essential nutrients, it can hinder weight gain. Additionally, certain foods may cause gastrointestinal distress, leading to symptoms like diarrhea and gas.

4. Psychological Factors: Sometimes, anxiety or stress can affect appetite and digestion, leading to gastrointestinal symptoms and difficulty in gaining weight.


Recommendations for Weight Gain
1. Consult a Healthcare Professional: It’s crucial to consult with a healthcare provider, such as a gastroenterologist or a registered dietitian, who can evaluate your symptoms and possibly conduct tests to rule out any underlying conditions.

2. Dietary Adjustments: Focus on a balanced diet that includes:
- Caloric Surplus: Aim to consume more calories than you burn. Incorporate calorie-dense foods like nuts, seeds, avocados, and healthy oils.

- Frequent Meals: Eat smaller, more frequent meals throughout the day to increase your overall caloric intake without overwhelming your digestive system.

- Protein-Rich Foods: Include lean meats, dairy, legumes, and protein shakes to help build muscle mass.

- Avoid Trigger Foods: If certain foods exacerbate your gastrointestinal symptoms, consider eliminating them from your diet temporarily to see if your symptoms improve.

3. Hydration: Ensure you are well-hydrated, but try to avoid drinking large amounts of fluids before meals, as this can reduce your appetite.

4. Physical Activity: Engage in strength training exercises to build muscle mass. This can help you gain weight in a healthy manner and improve your overall well-being.

5. Monitor Your Symptoms: Keep a food diary to track what you eat and how it affects your gastrointestinal symptoms. This can help identify any food intolerances or patterns that may be contributing to your issues.

6. Consider Probiotics: Probiotics may help improve gut health and balance the microbiome, potentially alleviating some gastrointestinal symptoms.


Conclusion
Gaining weight can be challenging, especially when gastrointestinal issues are present. It’s essential to address any underlying health concerns that may be contributing to your symptoms. By working with healthcare professionals and making targeted dietary and lifestyle changes, you can create a plan that supports healthy weight gain while managing your gastrointestinal health. Remember, patience and consistency are key, and it’s important to prioritize your overall health in the process.
