Sometimes you may notice small red dots on your skin, which can be a cause for concern. These red dots may be harmless, but sometimes they may indicate a health problem that needs attention. In this article, we will learn about the possible causes of red dots on the skin and how to deal with them.
1 Vasculitis (blood rash)
One of the common causes of red dots on the skin is inflammation of the small blood vessels, which occurs when blood leaks from the small blood vessels under the skin. This condition is known as blood rash, and is often the result of injury or excessive pressure on the skin. It may occur as a result of falls or minor injuries, and it may also appear in people who are exposed to excessive pressure for long periods, such as people with high blood pressure or borderline syndrome.
2 Skin allergies
A rash resulting from allergies can appear in the form of red dots. This allergy may be the result of the skin’s reaction to foods, medications, or chemicals found in cosmetics or detergents. Contact with allergens can cause skin irritation and the appearance of red dots, in addition to itching or swelling.
3 Acne
Acne can sometimes appear as small red dots, especially in the inflammatory stages of the disease. Acne occurs when the skin pores become clogged with oils and dead skin, causing inflammation in the hair follicles. Acne can also be accompanied by pimples or blackheads.
4 Varicose veins
When the blood vessels in the skin dilate due to poor circulation, red or bloody dots may appear on the skin, especially in the legs. This is caused by blood accumulating in the weak vessels and leads to the appearance of red dots, sometimes accompanied by a feeling of heaviness or swelling in the legs.
5 Septicemia or bacterial rash
In rare cases, red dots on the skin may indicate a bacterial or viral infection such as septicemia or scarlet fever. In these cases, the red dots are a rash resulting from the spread of the infection in the body.
6 Skin injury or bruise
When the skin is injured or bruised, red dots may appear on the skin due to blood leaking from small blood vessels into the tissues under the skin. These red dots are usually harmless and will go away over time.
7 Thrombocytopenia (blood clots)
Thrombocytopenia is a condition in which there are fewer platelets in the blood, making the blood vessels more fragile and causing blood to leak into the skin. In this case, small red dots may appear under the skin, known as a myxomatous rash.
8 Diabetes
Sometimes, a rash of red dots may appear due to diabetes-related problems, such as changes in blood circulation or dry skin. Diabetes is one of the factors that may contribute to the appearance of these dots in the event that blood sugar levels are not well controlled.
How to deal with red dots?
No matter the cause, if you notice red dots on your skin, you should first monitor other symptoms that may accompany them. If the red dots are related to an allergy or a minor injury, they may go away on their own. However, if the dots are accompanied by other symptoms such as fever, pain, or bleeding, it is best to consult a doctor for an accurate diagnosis.
Red spots on the skin can be a sign of a range of health conditions, from simple to complex. It is important to monitor these spots and look for other signs that may help determine the underlying cause. If you are concerned about red spots or if they are associated with unusual symptoms, you should consult a doctor for appropriate treatment.
