How Serious Is Raynaud’s disease?

When blood flow returns, the skin turns red, and may throb or tingle. In very rare, severe cases, the loss of blood flow can cause ulcers or tissue death, but usually, Raynaud’s is not dangerous —it’s just painful and frustrating.

What is the difference between Raynaud’s disease and Raynaud’s syndrome?

Primary Raynaud’s(or Raynaud’s disease) happens without any other illness behind it. The symptoms are often mild. Secondary Raynaud’s (Raynaud’s syndrome, Raynaud’s phenomenon) results from another illness. It’s often a condition that attacks your body’s connective tissues, like lupus or rheumatoid arthritis.

Where does Raynaud’s disease come from?

Raynaud’s disease is caused by peripheral blood vessels overreacting to cold. The condition affects 5-10 percent of Americans. Maurice Raynaud first described the disease in 1862. Females and people living in colder climates are more often affected.

What foods to avoid if you have Raynaud’s?

Always try to maintain a balanced, healthy diet and avoid caffeine and alcohol. Some food supplements have helped Raynaud’s sufferers, including evening primrose oil, gingko biloba and fish oils. Certain foods are also believed to help, like ginger, garlic and spicy food.

Why do I suddenly have Raynaud’s?

Why does it happen? Raynaud’s is usually triggered by cold temperatures, anxiety or stress. The condition occurs because your blood vessels go into a temporary spasm, which blocks the flow of blood. This causes the affected area to change colour to white, then blue and then red, as the bloodflow returns.

What vitamins are good for Raynaud’s?

These supplements may help:

  • Omega-3 fatty acids, found in fish oil, may reduce symptoms in people with primary Raynaud’s, according to one study.
  • Evening primrose oil (EPO).
  • Inositol hexaniacinate, a form of vitamin B3 or niacin, may reduce frequency of Raynaud’s attacks.
  • Magnesium opens up blood vessels.

What is the best medication for Raynaud’s?

Calcium channel blockers are the class of drugs most widely used for treatment of Raynaud syndrome—especially the dihydropyridines (eg, nifedipine, nicardipine), which are the most potent vasodilators. Nifedipine is the customary first choice.

What diseases are associated with Raynaud’s?

The diseases most often linked with Raynaud’s are autoimmune or connective tissue diseases such as:

  • Lupus (systemic lupus erythematous)
  • Scleroderma.
  • CREST syndrome (a form of scleroderma)
  • Buerger disease.
  • Sjögren syndrome.
  • Rheumatoid arthritis.
  • Occlusive vascular disease, such as atherosclerosis.
  • Polymyositis.

Can Raynaud’s affect your fingernails?

Raynaud’s phenomenon is a disorder, causing discolouration of the fingers. It is thought to be related to vasospasm. It can also affect the toes and other areas. The nails become brittle with longitudinal ridges.

How do you get tested for Raynaud’s?

To tell the difference between primary and secondary Raynaud’s, your doctor might do a test called nailfold capillaroscopy. During the test, the doctor looks at the skin at the base of your fingernail under a microscope or magnifier to look for deformities or swelling of the tiny blood vessels.

Can vitamin deficiency cause Raynaud’s?

Abnormalities of magnesium metabolism have been reported in people with Raynaud’s disease. Symptoms similar to those seen with Raynaud’s disease occur in people with magnesium deficiency, probably because a deficiency of this mineral results in spasm of blood vessels.

Can Raynaud’s affect the brain?

When it’s cold outside, some lupus patients develop Raynaud’s, which is where the vessels over constrict and turn blue. If it’s warm, they can over dilate and turn red. The same phenomenon can occur in the brain. Over dilation can cause a headache and over constriction can produce a mental fog.
