Three common symptoms of insufficient stomach acid include:

Insufficient stomach acid, also known as hypochlorhydria, can lead to a variety of digestive symptoms because stomach acid plays a critical role in breaking down food and facilitating nutrient absorption. Nausea can occur as a result of food not being properly digested, leading to feelings of discomfort and queasiness. Strong fatigue is often observed in individuals with low stomach acid, as this condition can hinder the absorption of essential nutrients, such as iron and vitamin B12, leading to deficiencies that result in tiredness and lack of energy. Additionally, persistent bad breath can stem from undigested food fermenting in the stomach and intestines, causing an unpleasant odor. These symptoms collectively indicate that inadequate stomach acid levels may be contributing to digestive issues, making this answer a fitting representation of the common manifestations of insufficient stomach acid.
