Probiotics that improve absorption and aid in weight gain?


Hello Doctor, I am 22 years old, 174 cm tall, and weigh 50 kg.
My diet is normal, and I have hemolytic jaundice (I return for check-ups every six months, and currently, there are no issues).
Due to my low weight, I have consulted an endocrinologist, and after reviewing my blood tests, the doctor indicated that all related values are normal.
I am currently hoping to improve my intestinal absorption by taking probiotics.
I would like to ask the doctor: 1.
Which strains of probiotics are beneficial for weight gain? 2.
What other tests can be done to further assess my physical condition and investigate potential causes of my low weight?

Dr. Lin Minghui reply Gastroenterology and Hepatology


Hello, there are many types of probiotics available as supplements, and their effectiveness depends on individual constitution, as each person's microbiome analysis is different.
Current research has not definitively stated that supplementing with specific strains will lead to weight gain or loss; sometimes, the emphasis is on the balance of the microbiota.
This area is still under investigation.
Common probiotics include Lactobacillus and Bifidobacterium, which can help maintain gastrointestinal health and balance the microbiota.

The reasons for being underweight are related to genetics, constitution, endocrine disorders (such as thyroid issues and diabetes), diet, lifestyle, exercise, and diseases.
It is advisable to monitor for hemolytic jaundice and avoid triggering factors.
Wishing you peace and health!
Sincerely,
Dr.
Ming-Hui Lin, Attending Physician, Department of Gastroenterology, Taoyuan General Hospital, Ministry of Health and Welfare.

Probiotics are live microorganisms that can provide health benefits when consumed in adequate amounts. While they are often associated with digestive health and weight loss, certain strains may also support weight gain, particularly in individuals who are underweight or have difficulty absorbing nutrients. In your case, given your height of 174 cm and weight of 50 kg, it is understandable that you are seeking ways to increase your weight healthily.


1. Probiotic Strains That May Help with Weight Gain
Certain probiotic strains have been studied for their potential role in weight management, including weight gain. Here are some strains that may be beneficial:
- Lactobacillus rhamnosus: This strain has been shown to help improve gut health and may assist in weight management. While it is often associated with weight loss, it can also support overall health, which may indirectly aid in weight gain.

- Lactobacillus reuteri: Some studies suggest that this strain can help improve gut health and may promote weight gain by enhancing nutrient absorption.

- Bifidobacterium lactis: This strain is known for its ability to improve gut health and may help in the absorption of nutrients, which can be beneficial for those looking to gain weight.

- Lactobacillus casei: This strain can help improve digestion and may also support the immune system, which is essential for overall health and weight management.

When considering probiotics for weight gain, it is essential to choose a high-quality product that contains these specific strains and to follow the recommended dosage.


2. Health Checks to Determine Underlying Causes of Low Weight
Since you have already consulted with a metabolic specialist and received normal blood test results, there are still several additional checks and assessments you can consider to further investigate the reasons behind your low weight:
- Nutritional Assessment: A registered dietitian can evaluate your dietary intake and identify any potential deficiencies or imbalances in your nutrition that may be contributing to your low weight.

- Gastrointestinal Evaluation: Since you mentioned wanting to improve nutrient absorption, it may be worthwhile to undergo tests for gastrointestinal conditions, such as celiac disease or inflammatory bowel disease (IBD), which can affect nutrient absorption.

- Thyroid Function Tests: Hyperthyroidism can lead to weight loss or difficulty gaining weight. A thyroid panel can help assess your thyroid hormone levels.

- Hormonal Assessments: Hormonal imbalances, such as those related to adrenal function or sex hormones, can also impact weight. Tests to evaluate these hormones may provide insights.

- Metabolic Rate Testing: A resting metabolic rate (RMR) test can help determine how many calories your body burns at rest, which can provide insights into your overall metabolism and caloric needs.

- Food Sensitivity Testing: Some individuals may have sensitivities to certain foods that can affect their ability to gain weight. Testing for food sensitivities may help identify any problematic foods.


Conclusion
Incorporating probiotics into your routine may be a helpful strategy for improving gut health and potentially aiding in weight gain. However, it is crucial to approach this in conjunction with a comprehensive evaluation of your overall health and nutritional status. Consulting with healthcare professionals, including a registered dietitian and possibly a gastroenterologist, can provide you with tailored recommendations and support as you work towards your weight gain goals. Remember, healthy weight gain should focus on building muscle and improving overall health rather than simply increasing body fat.
