Dizziness on the first day of quitting smoking

Dizziness on the first day of quitting smoking may be caused by hypoxia, withdrawal syndrome, hypertension, or other reasons. It is important to visit a hospital for an accurate diagnosis and to relieve discomfort through general management or medication. The specific causes are analyzed as follows:

1. Hypoxia

Dizziness may occur during the quitting process when there is a strong urge to smoke. When cigarettes burn, they consume large amounts of oxygen, reducing the oxygen content in the inhaled air and subsequently lowering blood oxygen levels. Engaging in aerobic exercises such as walking, tai chi, or outdoor activities can help improve symptoms.

2. Withdrawal Syndrome

Tobacco contains significant amounts of nicotine, to which smokers become dependent. Nicotine has certain stimulating effects that enhance alertness. When quitting abruptly, withdrawal symptoms may appear. In addition to dizziness, these may include headache, insomnia, decreased heart rate, increased appetite, weight gain, and constipation. Substitution strategies can be helpful, such as distracting attention and consuming sunflower seeds, fruits, milk, or other foods rich in vitamins B and C, which may also alleviate dizziness in individuals quitting smoking.

3. Hypertension

If a patient already has hypertension, anxiety and irritability during smoking cessation may trigger disease exacerbation. Elevated blood pressure increases vascular resistance, leading to symptoms such as dizziness and headache. It is recommended to take medications such as metoprolol succinate sustained-release tablets, nifedipine controlled-release tablets, or captopril tablets under medical supervision.

In addition, conditions such as cerebral ischemia, cervical spondylosis, or cerebral infarction may also cause dizziness during smoking cessation. Patients are advised to seek hospital evaluation for an accurate diagnosis and receive targeted treatment accordingly.
