What serum disturbances can occur due to the use of proton pump inhibitors (PPIs)?

Proton pump inhibitors (PPIs) are commonly used to reduce stomach acid production, which can help relieve conditions like gastroesophageal reflux disease (GERD) and peptic ulcers. However, long-term use of these medications has been associated with certain serum disturbances, particularly relating to electrolyte levels.

The correct answer highlights the potential for low magnesium and low sodium levels, commonly referred to as hypomagnesemia and hyponatremia, respectively. PPIs can interfere with the absorption of magnesium in the intestines. As a consequence, patients using PPIs, especially over extended periods, can experience decreased serum magnesium levels. This is clinically significant because magnesium is crucial for many bodily functions, including muscle and nerve function, and its deficiency can lead to various health issues.

Similarly, a concern with sodium levels arises from the pharmacological effects of PPIs, as alterations in gastric pH can affect the overall absorption and homeostasis of electrolytes in the body. While hyponatremia is less commonly emphasized compared to hypomagnesemia, it can still occur under certain conditions, especially in the context of overall electrolyte imbalance and fluid retention.

Thus, the identification of low magnesium and low sodium levels as a potential outcome of PPI use reflects well
