What foods can pregnant women eat to supplement potassium, and what are the symptoms of potassium deficiency?

Patient's question:

No

Doctor's answer:

The concentration of potassium in human serum is only 3.5 to 5.5 mmol/L, but it is essential for life activities. The main role of potassium in the human body is to maintain acid-base balance, participate in energy metabolism, and maintain the normal function of nerves and muscles. When the body lacks potassium, it can cause general weakness, fatigue, weakened heartbeat, dizziness, and blurred vision. Severe potassium deficiency can even lead to respiratory muscle paralysis and death. Additionally, low potassium levels can slow down gastrointestinal peristalsis, leading to intestinal paralysis, exacerbating anorexia, and causing symptoms such as nausea, vomiting, and abdominal distension.
