What are the symptoms of potassium deficiency from long-term use of antihypertensive drugs?

Long-term use of antihypertensive drugs leading to potassium deficiency typically causes symptoms such as tachycardia, physical weakness, and decreased appetite.

1. Tachycardia

Potassium deficiency can increase cardiac excitability, resulting in tachycardia. In severe cases, symptoms such as chest tightness and generalized weakness may also occur.

2. Physical Weakness

Potassium plays a key role in promoting carbohydrate and protein metabolism. When the body lacks potassium, insufficient energy production occurs, leading to neuromuscular dysfunction, as well as symptoms like lethargy, drowsiness, and mental confusion.

3. Decreased Appetite

Potassium deficiency affects gastrointestinal motility, causing symptoms such as anorexia, nausea, and vomiting. In severe cases, it may lead to intestinal paralysis and constipation.

In addition to the above symptoms, potassium deficiency may also result in reduced kidney function. If patients experience any of these symptoms, prompt medical evaluation is recommended. Diagnosis can be confirmed through blood tests to measure electrolyte levels.
