8 most dangerous and invisible diseases

Doctors identify several common diseases that develop almost gradually, late in making themselves felt with symptoms. They cause severe complications and early death. But with timely diagnosis, they respond well to treatment, which helps save a life for many years.

Specialists call such diseases “silent killers” for their ability to hide symptoms for a long time. Signs are masked behind fatigue and overwork at work, so the only way to prevent pathology is to visit a doctor and check-ups regularly.

8 most invisible diseases

Various changes in the body’s work occur with improper nutrition, physical inactivity, obesity. Diseases develop over the years, but most people ignore the first warning signs and symptoms.

High blood pressure

The World Health Organization calls high blood pressure the first cause of vascular disease, heart disease, and stroke in young people. The standard 120/80 mmHg was adopted as a basis, which can deviate minimally in the direction of increase after exercise or stress. The problem appears with obesity, prolonged use of hormonal drugs, abuse of salty or fatty foods.

Increased pressure develops gradually, so the body adapts to changes and surges. The person ceases to feel discomfort, occasionally noticing dizziness or a feeling of heat. The only measure of early diagnosis is the regular use of the tonometer, monitoring the indicators 3-4 times a week.

Cardiac ischemia

When cholesterol is deposited on the walls of the coronary vessels, the heart muscle does not receive enough blood, and cell death begins. Blood flow in the body slows down, the brain and internal organs experience oxygen deprivation, and myocardial infarction may occur. To not face ischemia, give up alcohol and smoking, get rid of excess weight, learn to deal with stress.


Doctors call the disease a “silent killer” for its ability to develop without overt symptoms. Intense thirst, weight loss, or vision problems appear already at the vascular damage stage, impairing kidney function. The metabolism slows down, and the body stops producing the hormone insulin. A simple blood glucose test helps to notice negative changes in time and prevent complications.

Intestinal tumor

The incidence of colorectal cancer is increasing around the world. Many patients go to stages 3-4, which leaves no chance for prolonged and active life. A tumor develops from a benign polyp in the colon over several years, but a colonoscopy can only detect growth. Therefore, doctors recommend that all patients over 45-50 years of age undergo the prophylaxis procedure without waiting for painful symptoms.


The disease leads to thinning of bone tissue, frequent and severe fractures that do not heal well. Osteoporosis develops with vitamin deficiency, lack of calcium and vitamin D in the diet, and is associated with hormonal disorders in women. Start prophylaxis after 40–45 years: do gymnastics, swim, lean on foods fortified with calcium, give up alcohol and nicotine.

Cervical cancer

The main cause of the disease is a woman’s reluctance to treat dysplasia at an early stage. The disease develops into an oncological one from injuries and inflammations of the cervix, which can be prevented in 90% of cases. At-risk are patients with obesity, a certain type of herpes virus, girls who are promiscuous. The best prevention method is an annual examination by a gynecologist, timely treatment of erosion and infections.

Skin cancer

The dangerous disease ranks second in mortality among cancer pathologies. It develops over the years with the abuse of tanning, frequent exposure to the open sun, excessive love for the tanning bed. If your skin develops unhealed sores, peeling, and redness, see a dermatologist immediately and do not self-treat.

Viral hepatitis

When liver cells are damaged by hepatitis B or C viruses, inflammation begins with irreversible changes in the organ’s structure. The disease can develop asymptomatically for several years, destroying the lobes and provoking fibrosis and cirrhosis. A blood test helps identify pathology early, which is recommended to be done at least one time per year.

The listed diseases, in many cases, are completely cured at an early stage. But the asymptomatic course, the absence of characteristic signs, leads to a late visit to doctors. It is important to remember about prevention, undergo an annual examination to prevent severe complications.
