Six Types of People Who Should Not Take Probiotics
A Review of People Who Are Not Suitable for Probiotic Use
Probiotics are widely known for their ability to regulate gut health and help relieve symptoms such as abdominal pain and diarrhea. As a result, they have become very popular in daily life, especially among people who experience gastrointestinal discomfort. However, probiotics are not suitable for everyone. Certain groups of people are advised to avoid using probiotics or to use them only under medical supervision. Below is a detailed look at six types of people who should not take probiotics.
1. People with Gastrointestinal Ulcers Accompanied by Active Bleeding
In general, patients with gastrointestinal ulcers who are experiencing active bleeding are not advised to use probiotics. Probiotics are live microbial preparations, and when ulcers with bleeding are present in the stomach or intestines, large numbers of live bacteria may enter the bloodstream through damaged blood vessels. This increases the risk of bacteremia, a potentially serious complication that may present with symptoms such as fever and chills.
Therefore, patients with actively bleeding gastrointestinal ulcers should wait until the ulcer has healed and only consider probiotic use under the guidance of a healthcare professional to avoid potential health risks.

2. People Allergic to Lactose or Fructose
Individuals who are allergic to lactose or fructose should also avoid using probiotics casually. Many probiotic products may contain residual lactose or fructose from the culture medium or as auxiliary ingredients. For people with allergies to these substances, taking probiotics may trigger allergic reactions such as skin rashes, itching, or even more severe systemic reactions, which can negatively impact health.
For those with known lactose or fructose allergies, it is important to carefully check product ingredient labels, choose allergen-free probiotic formulations, and consult a doctor or nutritionist if necessary to ensure safe use.
3. People with Acute Gastritis and Active Gastric Mucosal Bleeding
People who suffer from acute gastritis accompanied by active bleeding of the gastric mucosa are not recommended to take probiotics. Live probiotic bacteria may enter the bloodstream through bleeding capillaries in the damaged gastric mucosa, increasing the risk of bacteremia. As a result, probiotic use is not advised for this group.
4. People with Congenital Lactose Malabsorption
Individuals with congenital lactose malabsorption are generally not suitable candidates for probiotic supplementation. In such cases, taking probiotics may worsen absorption disorders and lead to metabolic complications. Excessive lactose accumulation may even result in lactic acidosis, posing additional health risks.
5. People with Immune Deficiency
People with immune deficiencies should use probiotics with extreme caution. In some cases, probiotic use may worsen the condition or increase the risk of infections. Therefore, individuals with immune system disorders are generally advised not to use probiotics unless specifically recommended and monitored by a healthcare professional.
6. People with Impaired Intestinal Barrier Function
Individuals with compromised intestinal barrier function are also not recommended to use probiotics. In such cases, probiotic supplementation may aggravate the condition and lead to various gastrointestinal discomforts. This group should exercise caution and seek medical advice before considering probiotic use.
Conclusion
The above six groups of people should be cautious when considering probiotics. If any discomfort or adverse reactions occur, medical professionals should be informed promptly. While probiotics can offer benefits such as supporting gut health, helping regulate lipid levels, and contributing to overall digestive balance, they are not universally suitable.
In addition to probiotics, some people may consider supplements such as glucosamine chondroitin calcium capsules, which typically contain calcium carbonate, chondroitin sulfate, D-glucosamine hydrochloride, and magnesium stearate. These supplements may help support calcium intake, increase bone density, nourish cartilage, and protect joint health, making them suitable for individuals who need long-term support for bone and joint health.
