While enjoying an occasional alcoholic beverage is unlikely to harm your health, drinking too much can have a significant negative impact on your body and health. So at what point does drinking alcohol become harmful to your health, and how much is considered heavy drinking.

Alcohol, also known as ethanol, is the main ingredient in alcoholic beverages such as beer and wine. To measure alcohol concentration, you can use a breathalyzer. Although the breathalyzer gives quick results, it is not as accurate as a blood alcohol test.

Many people who drink too much alcohol in the evening often have headaches the next morning when they wake up. In particular, patients who often suffer from migraines only need to consume a small amount of alcohol to cause a severe headache.

Blood alcohol concentration is defined as the percentage of alcohol (ethyl alcohol or ethanol) in a person's bloodstream. A BAC of 0.05% means there are 0.05 grams of alcohol in 100 ml of blood.

When talking about measuring alcohol concentration, people often think of alcohol concentration measuring devices using a blower. However, measuring alcohol concentration in the blood has more accurate results than breathing. So when is it done and what does the blood alcohol concentration measurement result mean?

Blood alcohol testing is often accompanied by blood glucose, complete blood count, and electrolyte tests to evaluate a number of clinical conditions associated with ethanol-induced disorders.
