Which of the following is NOT a symptom of hypoxia?

Hypoxia occurs when there is a deficiency of oxygen in the body tissues, which can lead to a variety of symptoms as the body struggles to compensate for the lack of oxygen. Dizziness, loss of vision, and poor coordination are all common symptoms associated with hypoxia.

Dizziness may result from lack of oxygen reaching the brain, leading to lightheadedness or a sense of vertigo. Loss of vision can occur due to insufficient oxygen affecting the functioning of the optic nerve or areas of the brain associated with vision. Poor coordination is also a result of hypoxia, as reduced oxygen levels can impair muscle control and motor functions.

In contrast, excessive appetite is not a symptom associated with hypoxia. Rather, during hypoxic conditions, the body's natural response is to reduce energy expenditure, which can lead to decreased appetite. Thus, stating that excessive appetite is a symptom of hypoxia is incorrect.
