Subacidity is a medical condition where there is a lower than normal production of stomach acid. This condition is also known as hypochlorhydria. There are several synonyms for subacidity such as reduced gastric acidity, low stomach acid, hypoacidity, and diminished acid secretion. The signs and symptoms of subacidity include bloating, gas, indigestion, and acid reflux. Individuals suffering from this condition may experience malabsorption of nutrients, leading to deficiencies. Treatment for subacidity involves over-the-counter antacids, supplemental digestive enzymes, and dietary changes. It is essential to speak with a medical professional to determine the underlying cause of subacidity and to develop a suitable treatment plan.
