Why Do I Feel Dizzy After Smoking a Cigarette?

Feeling dizzy after smoking may be caused by smoke irritation or conditions such as hypertension and cervical disc herniation. It is recommended to take targeted improvement measures based on the underlying cause. Here are some possibilities and corresponding suggestions:

1. Smoke Irritation

Cigarettes contain many harmful substances like nicotine, carbon monoxide, and tar. Smoking reduces the oxygen content in the blood, leading to insufficient blood supply to the brain and symptoms like dizziness and nausea. Reducing smoking or quitting altogether, along with adequate rest, can help alleviate these symptoms.

2. Hypertension

Failure to take antihypertensive medication regularly or significant emotional fluctuations can elevate blood pressure. Smoking further causes vasoconstriction, resulting in symptoms like dizziness, headache, and palpitations. Medications such as Nitroglycerin Tablets and Irbesartan Tablets can be prescribed by a doctor to manage these symptoms.

3. Cervical Disc Herniation

Compression of the vertebral artery in the neck disrupts blood flow, causing cerebral circulatory ischemia, ischemia, and hypoxia of brain cells. Smoking may exacerbate these conditions, leading to dizziness, limited neck and shoulder mobility, shoulder and back pain, and numbness and tingling in the upper limbs. Medications like Jingfukang Granules, Diclofenac Sodium Sustained-Release Capsules, and Celecoxib Capsules can be prescribed by a doctor for treatment.

Other potential causes of discomfort after smoking include cerebral arteriosclerosis and cerebral infarction. If symptoms persist or worsen, it is advisable to seek medical attention promptly for diagnosis and treatment.
