I78: Diseases of capillaries

Diseases of the capillaries refer to a group of medical conditions that affect the smallest blood vessels in the body, known as capillaries. These diseases can occur from a variety of causes including genetics, infections, and other circulatory system diseases. One may face difficulties in the flow of blood due to capillary diseases, which can result in the insufficient supply of oxygen and nutrients to the tissues. Common symptoms often vary based on the specific capillary condition but may include skin changes such as redness or discoloration, swelling, and in some cases, pain. Progression of these diseases also fluctuates based on individual circumstances and can range from gradual to rapid progress. It's crucial to remember that capillary diseases do not only affect the visible capillaries, such as those seen in the skin, but can also impact other internal organ systems as well.
