Why do I feel dizzy and have palpitations after drinking tea?

Generally, dizziness and palpitations after drinking tea may be caused by factors such as tea polyphenols, insufficient cerebral blood supply, or hypokalemia. These symptoms can usually be managed through medication and lifestyle improvements.

1. Tea polyphenols: Tea polyphenols are substances abundant in tea that can stimulate the sympathetic nervous system, often causing symptoms such as increased heart rate, dizziness, and blurred vision, which may lead to dizziness and palpitations after tea consumption. It is recommended that patients stop drinking tea immediately, remain calm, and avoid consuming overly strong tea in daily life.

2. Insufficient cerebral blood supply: This condition is usually caused by factors such as cerebral atherosclerosis or hypertension, commonly accompanied by symptoms like headache, dizziness, nausea, and vomiting, and may also result in dizziness and palpitations after drinking tea. Patients are advised to take medications such as aspirin tablets or rosuvastatin calcium tablets under medical guidance. In daily life, they should maintain a light diet and avoid strong tea and high-fat foods such as fatty meat and organ meats.

3. Hypokalemia: Hypokalemia typically results from inadequate potassium intake and is often associated with arrhythmia, fatigue, muscle weakness, and headache; it may also contribute to dizziness and palpitations after tea consumption. Patients should take medications such as potassium chloride sustained-release tablets or potassium chloride tablets under medical supervision.
