Although the benefits of caffeinated beverages have been proven, some illnesses may require you to give up your favourite black drink to stay healthy.

Inflammatory bowel diseases

These complaints are chronic, autoimmune conditions that can affect the small and large intestines. These include Crohn's disease and ulcerative colitis. Eating habits have a major influence on the condition of the affected person, and coffee drinking should be avoided during the active phase of the disease as it can increase diarrhoea.
 

Reflux
 

If you often experience a burning, stinging sensation around the mouth of your stomach after meals, there's a chance you may be suffering from reflux, one of the most common digestive diseases of our time. In this condition, stomach acid backs up into the oesophagus and irritates it.
 

Cardiovascular diseases
 

Although caffeine raises blood pressure and heart rate, it is not necessarily bad for your cardiovascular health. However, if you have high cholesterol, you should be wary of coffee because the compound cafestol in it increases the amount of the so-called bad cholesterol, LDL cholesterol. And too much cholesterol is a precursor to blood vessel and heart disease.
 

Epilepsy
 

According to doctors, excessive coffee consumption can increase the risk of epileptic seizures by stimulating the central nervous system, affecting brain activity.
 

Panic disorder
 

As with epilepsy, panic sufferers and people with intense anxiety should stop drinking coffee regularly, or at least switch to decaffeinated black. Caffeine's brain-stimulating effects can increase the frequency of panic attacks.
