The skin is not only a physiological barrier between the "inner world" of a person and the external environment. If in time and correctly recognize such signs, you can prevent the development of severe internal diseases, which, without timely treatment, can lead to the most serious consequences for humans.
We present you the top 10 changes on the skin, indicating the presence of diseases.
10. Swelling and turning blue of veins in the legs
A similar symptom suggests that some of your venous vessels undergo structural changes that negatively affect their functional ability. Varicose veins are not only a cosmetic defect, but also swelling by the end of the day, severe pain, cramps. Also, this disease is fraught with the development of a life-threatening condition - venous thrombosis.
What are the causes of varicose veins? The essence of such a disorder is a violation of the valves, which determine the direction of blood flow. If for some reason their work is disrupted, then the venous blood begins to stagnate in the vessels, because of which the veins are deformed.
9. Yellowish skin (especially palms and heels)
An obvious yellowish skin tone can be a sign of carotinemia (increased concentration of carotene in the blood). Most often, this condition develops as a result of functional thyroid insufficiency. Low thyroid hormone levels lead to an excessive increase in beta-carotene concentration. By itself, this substance is not toxic to humans, and even on the contrary, it has a lot of useful properties, however, excess of carotene in the blood can have a very negative effect on health.
8. Brownish spots on the lower leg
Most of us, from time to time, kick our feet on random objects on the road. Of course, in a healthy person, such accidents do not lead to the development of any disturbances. But in a person with diabetes mellitus, such damage causes a violation of the integrity of small vessels, which is manifested by the appearance of brown pigmentation, which in medicine is called “diabetic dermopathy”.
7. Violet foci and single spots
A similar phenomenon can be a hemorrhagic rash that occurs due to small subcutaneous hemorrhages. The causes of such a rash are usually blood or scurvy diseases (lack of vit. C). In older people, purpura may appear as a result of thinning of the subcutaneous tissue layer. In addition, with age, the resistance of the skin to the negative effects of the sun, as well as the walls of blood vessels, sharply decreases, in turn, become more fragile.
6. Skin cracking in the sun
Physiological intolerance to sunlight in world clinical practice is extremely rare. More often, the skin becomes inflamed in the sun due to the intake of certain groups of medicinal substances, which include photosensitizing components. Such substances increase the sensitivity of the skin to light, as a result of which, after a person is exposed to the open sun, areas of inflammation appear on his skin.
Dermatologists claim that this disorder also occurs in residents of the northern regions. During the winter, which in these parts can last about 9 months a year, such people do not experience any problems. However, in the summer months they notice the appearance of characteristic rashes on their bodies.
5. Skin tingling, rash on one side of the face or body
This symptom is characteristic of a skin disease called the herpes zoster. The causative agent in this case may be the chickenpox virus (chickenpox). In 80% of people who have had chickenpox, the virus enters the nerves and continues to function there in a latent state. When one or more provoking factors, such as stress, an infectious process, the use of certain drugs (for example, those prescribed for cancer or organ transplantation), weakened immunity, the virus can be activated again, which leads to symptoms of shingles.
4. Persistent itching without rash
Itching can occur for various reasons. However, if, in the presence of severe itching, no external signs of skin diseases are observed, then probably a similar phenomenon is associated with the development of a serious oncological disease - lymphoma. Also, the symptoms of this disease are an increase in cervical, axillary and subclavian lymph nodes.
3. Long dark lines on the palms
This symptom indicates adrenal insufficiency. This disorder is called Addison's disease. In addition, the appearance of hyperpigmentation in the area of skin folds, scars, and nasolabial triangle is characteristic of this ailment. Also, in patients suffering from Addison's disease, there is a persistent decrease in blood pressure and a decrease in the concentration of salt in the blood.
2. Pallor of the skin, especially against the background of turning blue under the nails
This symptom indicates the development of anemia, or, as it is also called - anemia. Patients suffering from anemia are characterized by the presence of pallor of the skin. This disease occurs as a result of iron deficiency, chronic blood loss (can occur with diseases of the gastrointestinal tract, female reproductive system, etc.), starvation, oncological blood diseases, and hereditary diseases.
1. An unbearably itchy rash
The foci of multiple small blisters that most often form in the forearms (closer to the elbow), on the knees, buttocks, lower back, face and scalp, cause severe itching, causing great discomfort to the person. A similar symptom occurs with gluten intolerance. Experts say that about 25% of the people living on our planet suffer from this congenital disorder.
