Appetite stimulants and digestive aids can help increase body weight?


I have a body type that doesn't gain weight easily, but I do not have any gastrointestinal diseases (I have seen a doctor).
Previously, a friend recommended a digestive supplement, which I took after lunch and dinner for a month.
During that time, my weight gradually increased by 3 to 4 kilograms.
However, after I stopped taking it, my weight slowly decreased again by about the same amount.
Therefore, I am considering using this type of digestive supplement to help improve my gastrointestinal absorption and increase my weight.
I am concerned about whether long-term use could be harmful to my health.

Hello! Lactic acid bacteria are also a type of health supplement.
They can aid in digestion and improve gut health, making them beneficial for individuals with poor digestive absorption, as they help with nutrient uptake.
There are various types of lactic acid bacteria available on the market, and it is generally recommended to switch between different strains every three to six months to introduce diverse beneficial bacteria to the gut.
Since health supplements are essentially food, consuming them daily over the long term is generally safe.
However, it is important to be aware of any underlying metabolic issues or kidney problems.

Digestive supplements can indeed play a role in helping individuals who struggle to gain weight, particularly those with a fast metabolism or those who may not be absorbing nutrients effectively. However, it is essential to approach the use of these supplements with caution and to understand their potential benefits and drawbacks.

Firstly, it’s important to clarify what digestive supplements are. They typically include enzymes, probiotics, and other compounds designed to enhance digestion and nutrient absorption. For someone who has a fast metabolism or difficulty gaining weight, these supplements can help improve the efficiency of digestion, potentially allowing for better absorption of calories and nutrients from food. This can be particularly beneficial for individuals who may have a higher caloric requirement due to their activity levels or metabolic rate.

In your case, you mentioned that you experienced a weight gain of 3 to 4 kilograms while using a digestive supplement but lost that weight once you stopped taking it. This fluctuation is not uncommon and can be attributed to several factors. When you take digestive supplements, they may help improve your appetite or enhance the absorption of nutrients, leading to weight gain. However, once you stop taking them, your body may revert to its previous state, especially if your dietary habits remain unchanged.

Regarding the long-term use of digestive supplements, there are a few considerations to keep in mind. While many digestive supplements are generally safe for short-term use, long-term use can sometimes lead to dependency, where your body may become reliant on the supplements for proper digestion. This could potentially lead to issues if you decide to stop taking them. Additionally, some supplements may cause side effects, such as gastrointestinal discomfort, bloating, or diarrhea, particularly if taken in excess.

It’s also crucial to consider that weight gain should ideally come from a balanced diet that includes a variety of nutrients rather than solely relying on supplements. A diet rich in whole foods, including healthy fats, proteins, and carbohydrates, can provide the necessary calories and nutrients to support healthy weight gain. Foods such as avocados, nuts, seeds, whole grains, and lean proteins can be beneficial additions to your diet.

If you are considering using digestive supplements to help with weight gain, it is advisable to consult with a healthcare professional or a registered dietitian. They can provide personalized recommendations based on your health status, dietary needs, and weight gain goals. They may also suggest alternative strategies for increasing your caloric intake, such as meal planning, incorporating calorie-dense foods, and ensuring that you are eating enough throughout the day.

In summary, while digestive supplements can assist in weight gain for some individuals, they should not be the sole strategy for achieving your weight goals. A comprehensive approach that includes a balanced diet, possibly enhanced by supplements under professional guidance, is the best way to ensure safe and effective weight gain. Always prioritize your overall health and well-being when considering any dietary changes or supplement use.
