About
Basics of raynaud's phenomenon
Raynaud's (pronounced "ray-NODES") phenomenon refers to episodic
color changes in the skin of the fingers and toes during exposure to
cold or in response to emotional stress. In some people, the ears,
lips, and nose may also be affected.
Although it is normal for blood flow to the fingers to be reduced in
extreme cold, people with Raynaud's phenomenon have difficulty on mild
days, in air-conditioned rooms, or when holding a cold drink. Episodes
may last for several minutes after the body becomes warm again.
When this condition occurs in the absence of disease, it is known as
"primary Raynaud's phenomenon." Approximately 10 percent of healthy
women have this form. Raynaud's may also occur with diseases in which
the blood vessels have been injured or when elements of the blood are
sluggish. This form is called "secondary Raynaud's phenomenon" and is a
feature of arthritis and related diseases such as scleroderma, lupus, rheumatoid arthritis, and others.
Immediate medical attention
In secondary Raynaud's phenomenon, sores called ulcers may develop
when blood does not flow adequately to the tissues. Examine feet and
hands daily to check for ulcers. If an ulcer develops, keep it clean
and covered and see a doctor right away.
Prognosis
Episodes of Raynaud's phenomenon usually occur only once in a while and typically don't cause permanent damage. Some people,
however, may have frequent and severe episodes.
Without treatment, secondary Raynaud's phenomenon can damage the
affected part of the body. When blood does not flow adequately to the
tissues, sores called ulcers may develop. If left untreated, these
sores can become infected and may take a long time to heal. This kind
of damage rarely happens in primary Raynaud's phenomenon. Therefore, it
is important to find out what type of Raynaud's phenomenon is present
so that the proper treatment can be applied to prevent damage.
Pain
Pain may occur during episodes of secondary Raynaud's phenomenon.Curability
Although there is no cure for Raynaud's phenomenon, the condition can be controlled and symptoms can be reduced in most cases.
Incidence
Raynaud's phenomenon can begin at any age, but primary Raynaud's
phenomenon typically begins during adolescence. If it begins in later
years, in men, or in association with other symptoms, the person with
Raynaud's phenomenon symptoms should see a physician for medical
attention and proper diagnosis.Prevention
A prevent with primary Raynaud's phenomenon can try to prevent
episodes. A person with secondary Raynaud's phenomenon can try to
prevent tissue damage. This can be done by protecting the body from
cold and avoiding aggravating factors, such as excessive emotional
stress, smoking, certain medications like nonselective beta-blockers,
use of industrial tools with violent vibration, and use of narcotics.
Anatomy
During an episode of Raynaud's phenomenon, the blood vessels in the
affected areas--usually the fingers and/or toes--become narrower for a
short time. This narrowing prevents the blood from flowing freely to
the affected area.Symptoms
As the blood flow decreases due to the narrowing of blood vessels, the following symptoms may be noted:
- Change of skin color in the affected area. First, the skin may turn
white because there is little blood in that area. Then it may turn blue
because the blood remains stagnant in the blood vessels due to improper
flow. Finally, the skin my turn red or purple as blood begins flowing
again. Sometimes skin may turn only white or blue.
- Numbness and/or coldness in the affected area as the blood flow slows. Pain may occur during episodes of secondary Raynaud's.
- Swelling, tingling, aching, warmth, and/or throbbing in the affected area as the blood begins flowing again.
Episodes of Raynaud's phenomenon usually occur only once in a while and typically don't cause permanent damage. Some people,
however, may have frequent and severe episodes.
Without treatment, secondary Raynaud's phenomenon can damage the
affected part of the body. When blood does not flow adequately to the
tissues, sores called ulcers may develop. If left untreated, these
sores can become infected and may take a long time to heal. This kind
of damage rarely happens in primary Raynaud's phenomenon. Therefore, it
is important to find out what type of Raynaud's phenomenon is present
so that the proper treatment can be applied to prevent damage.
Causes
Doctors aren't sure exactly what causes Raynaud's phenomenon. They do
know, however, that episodes are often triggered by cold temperatures
and sometimes by emotional stress, such as nervousness or excitement.
There are many causes of secondary Raynaud's phenomenon, including
inflammation of the blood vessels (called vasculitis) or blockage of
blood vessels.Diagnosis
To diagnose Raynaud's phenomenon, a doctor may:
- perform a thorough general physical examination and ask questions
about symptoms (as already mentioned, Raynaud's phenomenon may occur as
a symptom of other illnesses)
- take blood samples to test for other illnesses that may have similar symptoms
- examine the fingers under a special microscope to look for abnormal blood vessels.
- follow the patient's health status over the course of several visits.
Treatment
Most people with primary Raynaud's phenomenon don't require medical
treatment, although many choose to take medication during the winter
months. People with secondary Raynaud's phenomenon are at risk for
fingertip ulcers and tend to have active symptoms all year long.
The goal of treatment of Raynaud's phenomenon is to prevent episodes
and, in secondary Raynaud's phenomenon, to prevent tissue damage. This
can be done by protecting the body from cold and avoiding aggravating
factors, such as excessive emotional stress, smoking, certain
medications like nonselective beta-blockers, use of industrial tools
with violent vibration, and use of narcotics. In some cases, a doctor
may prescribe medication.
Self-management
A person with Raynaud's phenomenon can treat or manage their own
condition by protecting the body from excessive cold, and by protecting
the skin.
Cold protection
To avoid episodes a Raynaud's phenomenon, the entire body should be
warm at all times. Follow these tips to avoid getting too cold:
- Dress warmly in layers of loose-fitting clothes, especially during cold weather and during changes of season.
- Wear a hat in cold weather, because body heat is lost through the scalp. Cover your face and ears with a scarf.
- Wear loose-fitting boots and shoes that won't cut off the blood circulation.
- Wear heavy socks or layers of socks.
- Wear mittens -- they are warmer than gloves.
- Always keep a sweater or jacket nearby, even during the summer. It may be cold enough to need it in air-conditioned buildings.
- Use flannel sheets or layers of blankets. Use an electric blanket
to warm the sheets before getting into bed. If your hands and feet get
cold while sleeping, wear mittens and socks to bed.
- Keep the rooms used most often at a comfortable temperature.
- Start running the bath or shower water well before bathing so you
don't touch the cold water. Keep the bathroom door closed so steam will
warm the room.
- Ask family and friends to help. For example, let someone else get
the newspaper from outside or start the car on a cold day. Avoid
household tasks that require putting hands in cold water.
- Wear gloves or mittens to reach into the freezer.
- Use insulated containers, gloves, or napkins to hold cold drinks or food.
- Rinse and peel vegetables with warm water.
- Use chemical heat packs to supplement mittens and warm clothing.
Skin protection
Poor blood flow may make skin dry. It may also cause cuts, cracks,
or sores to heal more slowly than usual. These tips can help protect
skin:
- Use lotion with lanolin on hands and feet every day to keep the skin from chapping or cracking.
- Wash with a mild, creamy soap. Clean between fingers and toes, but don't soak them.
- Examine feet and hands daily to check for ulcers. If a ulcer develops, keep it clean and covered. See a doctor right away.
- Protect fingernails and toenails. Use a lotion to keep the cuticles
soft. Don't cut the cuticles with scissors or use sharp instruments to
push them back. Instead, gently push them back with a cotton swab
soaked in cuticle remover. Carefully cut hangnails and file your nails
in a rounded fashion to the tips of your fingers.
- Wear rubber gloves while washing dishes.
- Take care when doing activities that put pressure on the
fingertips, such as using a manual typewriter or playing the guitar or
piano. This kind of pressure may cause your blood vessels to narrow,
thus triggering an episode.
- Wear clothes made of natural fibers, such as cotton and wool. These draw moisture away from the skin.
Other tips
- Don't smoke. Chronic smoking causes blood to narrow. Medications to treat Raynaud's may not be as effective in smokers.
- Try to avoid emotional stress. Ask a doctor about relaxation techniques and other stress reduction methods.
- Because certain drugs may cause blood vessels to narrow, all the
doctors that work with a person with Raynaud's phenomenon should be
told about the condition, and medications should be discussed. Working in partnership with a doctor may help determine which drugs and treatment are most suitable for each person.
- A warmer climate will not cure Raynaud's phenomenon, but it may cut
down on the occurrence of episodes and reduce the risk of developing
ulcers on fingers. If you consider moving to a warmer climate, you'll
need to decide if the benefits outweigh the expenses and complications
of relocating.
- Look into biofeedback training. It may help control Raynaud's
phenomenon. Biofeedback
may also help reduce pain and promote relaxation. A doctor should be
able to discuss if it would be helpful and where to find training.
Handling an episode
If an episode a Raynaud's phenomenon occurs, stay calm and get your
whole body warm by going indoors or by putting on warm clothing. Then
follow these steps:
- Gently warm the fingers and toes as soon as possible. Placing hands under the armpits often helps.
- Wiggle the fingers and toes. Move or walk around to help blood flow freely.
- When hands start to feel cold, held them above the head. They swing them around as in throwing a softball.
- Run warm--not hot--water over the fingers or toes until
normal skin color returns. Do not use a hot water bottle or heating
pad, which may damage the skin.
Exercise and therapy
Exercise may have some benefit to people with Raynaud's phenomenon. A
doctor may be able to advise if an aerobic exercise program would be
helpful.Medications
No drugs are specifically approved by them U.S. Food and Drug
Administration for treatment of Raynaud's. However, many drugs used to
treat high blood pressure or angina pectoris have been shown effective
and safe in treating Raynaud's phenomenon. These include calcium
channel blockers such as nifedipine, amlodipine, isradipine, and others.
Some of these medications may have side effects, such as headache,
palpitations, lightheadedness or dizziness, or fluid retention. Contact
a doctor if questions arise about side effects from medications or
questions about their use.
Surgery
In rare cases, a doctor may recommend sympathectomy to treat Raynaud's
phenomenon. This operation involves cutting the nerves that may be
making the narrowing of the blood vessels worse. The procedure is done
mainly for secondary Raynaud's phenomenon and usually is not necessary.Credits
