Which of the following is NOT a sign of hypokalaemia?

Hypokalaemia is characterized by low potassium levels in the blood, which can lead to various physiological manifestations. Cardiac arrhythmias can occur as potassium is crucial for maintaining normal cardiac rhythm; therefore, any imbalance can directly affect heart function. Abdominal distension is also a common symptom, as potassium deficiency can lead to decreased muscle contractions in the gastrointestinal tract, causing motility issues. Nausea and anorexia can result from electrolyte imbalances, including hypokalaemia, as they affect the normal functioning of digestive processes and can lead to gastrointestinal distress.

Weight loss, while it can be associated with a variety of health conditions, is not a direct sign of hypokalaemia. Weight loss is more indicative of caloric deficiency or other metabolic issues rather than an electrolyte imbalance. Thus, identifying weight loss as the symptom that does not correspond with hypokalaemia helps clarify the specific physiological impacts of low potassium levels.
