Coffee has an aroma that is different from other drinks. Although some people may not be used to this taste, those who love to drink it love it very much, especially when they are listless and have not slept well but have heavy work to deal with, many people will choose to drink a cup of coffee to help improve work efficiency. In fact, some groups are not suitable for drinking coffee, especially patients with certain diseases.

So which groups are not suitable for drinking coffee?

1. Patients with kidney deficiency

Coffee is not suitable for patients with kidney deficiency because coffee contains a lot of caffeine, which can not only stimulate the brain nerve tissue and produce excitement, but also stimulate the metabolism of the kidneys. Especially for middle-aged men and women, as they age, they will have more or less symptoms of kidney deficiency. If they drink a lot of coffee frequently, it will further aggravate the symptoms of kidney deficiency.

2. Patients with four highs

Patients with the three highs refer to those with high blood sugar, high blood lipids, and high cholesterol. Currently, with the improvement of people's living standards, the number of patients with the three highs is showing a straight upward trend, and even a fourth high, high uric acid, has appeared. Pure coffee is bitter, so many people like to add some flavoring products to increase the concentration of the taste when drinking coffee, such as sugar cubes and milk tablets. It is true that the addition of these things can increase the richness and sweetness of the coffee taste, but it also invisibly increases the intake of a large amount of protein and sugar, which is not conducive to patients with the four highs to delay the symptoms of the disease.

3. Middle-aged and elderly people

Middle-aged and elderly people are older, and both their physical fitness and sleep quality show a significant downward trend. Many elderly people even have serious insomnia symptoms. Coffee can excite the human nervous tissue and aggravate the autonomic nervous system disorders of middle-aged and elderly people.

4. People with mental illness

Relatively speaking, common minor physical illnesses can be cured quickly by taking medicine or other methods, but the treatment of mental illness is relatively complicated. Drug treatment is only one aspect of it, and a lot of auxiliary treatments in other aspects are also needed. In order to help patients with mental illness recover quickly, they should try to stay away from stimulating drinks such as coffee, otherwise it may aggravate the symptoms of mental illness and cause more serious sleep disorders.

5. Patients with heart disease

Coffee can also stimulate the function of the heart. Heart disease patients already have impaired heart function, and the large amount of caffeine in coffee will further increase the stimulation to the heart.

From the above introduction, we can see that coffee is not suitable for patients with certain diseases, and coffee may even aggravate the condition. Patients should follow the advice of professional doctors and be cautious about coffee.
