Why low stomach acid leads to poor immunity
L
Low stomach acid, a condition known as hypochlorhydria, can potentially lead to an increased risk of infections for several reasons:
Impaired digestion of food: Stomach acid plays a crucial role in breaking down and sterilizing the food we consume. When acid levels are low, the digestive process may be compromised, leading to incomplete digestion of proteins, fats, and carbohydrates. This can create an environment in the intestines that is more conducive to the growth of harmful bacteria and pathogens.
Reduced sterilization of ingested pathogens: One of the primary functions of stomach acid is to kill bacteria, viruses, and other microorganisms that may be present in the food and liquids we consume. Adequate stomach acid helps protect the body from infections by neutralizing many potential pathogens before they reach the intestines. When stomach acid is low, this protective mechanism is weakened, making it easier for harmful microorganisms to survive and potentially cause infections.
Altered gut flora balance: Stomach acid also helps maintain the balance of beneficial and harmful bacteria in the gut. When acid levels are low, the pH in the stomach and intestines may become less acidic, favoring the growth of pathogenic bacteria and yeast over beneficial probiotic bacteria. This can disrupt the normal gut microbiome and increase the risk of infections.
Decreased absorption of nutrients: Low stomach acid can hinder the absorption of essential nutrients, such as vitamins and minerals, from food. Many of these nutrients are important for a healthy immune system. When nutrient absorption is compromised, the immune system may become less effective at defending against infections.
Weakened barrier function: Adequate stomach acid is necessary for maintaining the integrity of the gastric mucosal barrier, which helps protect the stomach lining from damage by acid and pathogens. When stomach acid is low, this barrier may become more vulnerable, potentially allowing pathogens to penetrate and cause infections.
It's important to note that while low stomach acid can increase the risk of infections, it is not the sole factor involved in immune system function. Other factors, such as overall health, diet, hygiene, and immune system strength, also play significant roles in determining susceptibility to infections
