The main signs of poor blood circulation are named

According to scientists' estimates, up to 20% of people worldwide suffer from Raynaud's disease . This condition is characterized by long-term spasm of terminal arteries and arterioles, usually of the upper extremities. As a result, blood circulation is disturbed, which causes various problems.

In particular, numbness of the fingers may occur in response to cold temperatures or stress. In addition, the disease affects other parts of the body, such as the ears or lips.

In Raynaud's disease, the smaller arteries that supply blood to the skin become narrowed, limiting blood flow. During an attack, the affected areas often turn white, then turn blue and feel cold or numb.

As the body warms and circulation improves, the affected areas may become red, throbbing, tingling, or swollen. The main signs of Raynaud's disease include:

• cold fingers or toes;
• skin color change in response to cold or stress;
• numbness, feeling tingling or burning pain when warmed up.

While doctors do not know exactly what causes Raynaud's attacks. However, one of the main triggers is considered to be the effect of low temperatures – for example, putting your hands in cold water. In some people, emotional stress can lead to an attack.

As for treatment methods, they are both conservative and surgical. The first include the use of vasodilator drugs, surgical ones include sympathectomy.
