Introduction
Dizziness and nausea in enclosed spaces may be caused by physiological factors, or by conditions such as anemia or claustrophobia, and targeted treatment should be based on the specific underlying cause. Besides these common causes, other factors—such as depression, hypertension, or coronary atherosclerotic heart disease—may also be responsible. Patients should seek timely medical attention to avoid delaying diagnosis and treatment.
Dizziness and nausea in enclosed spaces may be caused by physiological factors, or could result from conditions such as anemia or claustrophobia. Targeted treatment should be based on the specific underlying cause. Detailed analysis is as follows:
1. Physiological Factors
In enclosed spaces with poor air circulation and reduced oxygen levels, individuals may experience mental tension, leading to dizziness and nausea. This is considered a normal physiological response and usually resolves spontaneously without requiring excessive concern.
2. Disease-Related Factors
a. Anemia
Patients with anemia may suffer from insufficient cerebral blood supply. In confined spaces, heightened anxiety can further reduce blood flow velocity, worsening cerebral hypoperfusion and triggering symptoms such as dizziness and nausea. These may be accompanied by pale skin and fatigue. Under medical guidance, patients can take medications such as ferrous succinate tablets or iron dextran oral solution to alleviate symptoms.
b. Claustrophobia
This is a relatively common psychological disorder, often associated with personal experiences and personality traits. It causes intense fear when individuals are in enclosed spaces, resulting in symptoms including dizziness, nausea, cold sweats, and trembling of the hands and feet. Treatment under medical supervision may include medications such as paroxetine hydrochloride tablets or oryzanol tablets.
Besides the above common causes, other conditions—such as depression, hypertension, or coronary atherosclerotic heart disease—may also contribute. Patients should seek timely medical evaluation and treatment to avoid delays in managing their condition.
