:> Most likely effective for <:

:> Potentially effective for <:

Diabetes. Type 2 diabetes is less common in people who consume more coffee. Every cup of coffee consumed reduces the risk. Coffee drinkers with type 2 diabetes may be less likely to die.

Heart beat stop For people who do not have heart disease, drinking caffeinated coffee may reduce the risk of heart failure.

Any cause of death can cause death. A slightly lower chance of death from any cause or heart disease is associated with drinking coffee daily. It is not clear whether drinking coffee lowers your chances of dying from cancer.

:> Possibly Ineffective <:

Cancer of the esophagus. Drinking coffee does not reduce the risk of developing cancer in the esophagus.

-> Insufficient Evidence <:

Atrial fibrillation is an irregular heartbeat. The lower risk of atrial fibrillation when you drink more coffee is unclear.
Bladder cancer. Drinking coffee does not reduce the risk of bladder cancer.

Brain cancer. Early evidence suggests that people in Asia who consume more coffee are less likely to develop brain cancer.
Breast Cancer. Women who consume more coffee are not less likely to develop breast cancer.

Heart disease. It is not known whether coffee consumption lowers the risk of developing heart disease. This can reduce your chances of developing heart disease and your risk of dying from it.

Gallbladder disease. People who consume coffee with at least 400mg of caffeine daily are less likely to develop gallstones. Higher intake of caffeine linked to lower risk

Gout. Some evidence suggests that both decaffeinated and caffeinated coffees can help prevent gout. However, caffeinated coffee appears to be more effective.

Hearing loss. A slightly lower risk of hearing loss is seen in males who consume at least one cup of caffeine daily. This effect doesn't appear to be present in women who drink coffee daily.

High blood pressure. High blood pressure is less likely in people who have been drinking coffee for a long time. This benefit may be lost if you smoke. The most beneficial intake is 1-3 cups per day.

Taken by mouth: Coffee is often consumed as a beverage. Coffee in moderate quantities (approximately 4 cups per day) is safe for most people. However, it is possible to become ill if you consume more than that amount of coffee each day. Due to caffeine's high content, excessive consumption could cause side effects. Side effects that can occur include irregular heartbeat and headaches. If coffee is given to the bladder (rectally), it could be dangerous. There have been cases of death from coffee enemas.
