Why Do People Feel Dizzy After Chewing Betel Nut

Betel nut, a substance known for its addictive properties, is commonly consumed in regions such as Fujian, Guangdong, and Taiwan. There are several reasons why individuals may experience dizziness after chewing betel nut.

Increased Blood Pressure

One of the primary reasons is elevated blood pressure. Betel nut contains compounds that can stimulate the central nervous system, leading to temporary feelings of alertness and energy. However, frequent use can result in addiction, and with prolonged use, blood pressure may fluctuate significantly. Hypertension caused by regular betel nut consumption can lead to episodes of dizziness and lightheadedness.

Brain Vascular Expansion

Another contributing factor is the expansion of blood vessels in the brain. When the brain becomes more active due to the stimulating effects of betel nut, oxygen consumption increases. This heightened demand for oxygen can cause blood vessels to dilate, potentially resulting in a sensation of head fullness or discomfort, which some users interpret as dizziness.

Sleep Disruption

Betel nut functions as a stimulant, affecting neurotransmitter activity in the brain. It can trigger the release of excitatory amino acids like glutamate, increasing brain activity and metabolic demand. This overstimulation can interfere with sleep patterns, leading to insomnia. Lack of restful sleep often results in fatigue and dizziness the following day.

Withdrawal Symptoms

When the stimulating effects of betel nut wear off, withdrawal symptoms may occur. Without a continuous intake to maintain the heightened state, users may feel sluggish, tired, or disoriented. This drop in energy levels—combined with the body's adjustment to the absence of stimulation—can also contribute to feelings of dizziness.
