What is Raynaud’s Disease?
Raynaud’s disease causes spasms in small blood vessels in the fingers and toes. This limits the flow of blood to restricted areas, called vasospasm. In some cases, it also causes decreased blood flow to ears, nose, knees or toes. Raynaud’s can happen on its own or accompanied with other underlying diseases. Other names for Raynaud’s disease are:
- Raynaud’s phenomenon
- Raynaud’s syndrome
Women are more likely to have Raynaud’s disease than men. In addition to this, Raynaud’s syndrome treatment depends on its severity and whether an individual has other health conditions. The diseases that are most often associated with Raynaud’s are autoimmune or connective tissue diseases such as:
Note: For a majority of people, Raynaud’s disease is not disabling but can affect the quality of life.
How Raynaud’s Disease Affects Blood Circulation?
Raynaud’s Disease affects how blood flows to certain parts of the body, mainly the fingers and toes.
It happens because small blood vessels suddenly narrow. This is called a spasm. It is often triggered by cold or stress.
Here’s what happens step by step:
- Blood vessels tighten more than normal
- Blood flow drops for a short time
- Affected areas turn white, then blue
- As blood returns, they may turn red and feel painful or tingly
These episodes are temporary, but they can be uncomfortable.
Over time, frequent attacks can reduce oxygen supply to tissues. In severe cases, this may lead to skin damage or sores.
In simple terms, Raynaud’s doesn’t block blood completely. But it limits flow enough to cause visible colour changes and discomfort.
What are the Different Types of Raynaud’s Disease?
The two main types of Raynaud’s syndrome are:
- Primary Raynaud’s syndrome (also called Raynaud’s disease)
- Secondary Raynaud’s syndrome (also known as Raynaud’s syndrome)
Here’s what you need to know about the types of Raynaud’s disease:
Category | Raynaud’s disease (primary) | Raynaud’s disease (secondary) |
Cause | Unknown. Not associated with any underlying condition. | Underlying condition, medication or lifestyle factors. |
Symptoms | Generally mild (skin colour changes, numbness). Doesn’t cause skin ulcers. | May be mild or severe and can cause skin ulcers. |
Prevalence | More common | Less common |
Treatment | Lifestyle modifications | Targets underlying cause (may include medicines or procedures). |
Raynaud’s Syndrome Symptoms
Raynaud’s disease symptoms are episodic and a typical episode may last about 15 minutes. Raynaud’s syndrome symptoms can be different for each person and most commonly include:
- Fingers that turn white or pale and then blue, if exposed to cold or during stress and emotional upset. When the blood flow returns to normal, the hands are warmed, tingle and turn red.
- Hands that become swollen and painful when warmed.
- In severe cases, sores appear on the finger pads.
- In rare cases, long or frequent episodes can cause painful sores on fingertips. Rarely, lack of oxygen to the tissues can lead to gangrene (tissue death) that may need amputation.

Causes and Risk Factors of Raynaud’s Disease
Raynaud’s Disease happens when small blood vessels overreact and narrow too easily. The exact cause depends on the type.
Causes
Primary Raynaud’s (most common)
- No clear underlying disease
- Blood vessels are just more sensitive to cold or stress
Secondary Raynaud’s (more serious)
Caused by another condition, such as:
- Autoimmune diseases like Lupus or Scleroderma
Risk Factors
- Cold climate: Living in colder areas increases risk.
- Gender: More common in women.
- Age: Primary type often starts between 15–30 years.
- Family history: It can run in families.
- Smoking: Nicotine narrows blood vessels.
- Certain jobs: Regular use of vibrating tools (like drills or jackhammers).
- Medications: Some drugs can trigger or worsen symptoms:
- Beta-blockers
- Migraine medicines
- Decongestants
- Existing health conditions: People with autoimmune diseases are more likely to develop secondary Raynaud’s.
In simple terms, it’s either due to over-sensitive blood vessels or linked to another health condition, with lifestyle and environmental factors increasing the risk.
Triggers That Can Cause Raynaud’s Attacks
Raynaud’s Disease attacks usually start when blood vessels react too strongly to certain triggers.
Here are the common ones:
- Cold exposure: This is the main trigger.
- Cold weather, air conditioning, or even holding a cold drink can start an attack.
- Emotional stress: Stress or anxiety can cause blood vessels to tighten.
- Sudden temperature changes: Moving from a warm room to a cold space can trigger symptoms.
- Smoking: Nicotine narrows blood vessels and makes attacks more likely.
- Caffeine: Too much caffeine can also tighten blood vessels.
- Certain medicines: Some drugs can reduce blood flow, such as:
- Beta-blockers
- Migraine medicines
- Some cold medications
- Vibration or repeated hand use: Using tools that vibrate (like drills) can trigger episodes over time.
- Hormonal factors: It is more common in women, so hormones may play a role.
In short, anything that causes blood vessels to tighten can trigger an attack.
Raynaud’s Disease Diagnosis
A doctor diagnoses Raynaud’s disease based on an individual’s symptoms. A few diagnostic tests that a doctor may recommend to determine primary or secondary Raynaud’s syndrome and its causes are:
- CBC (Complete Blood Count): Blood test that checks for a range of conditions.
- ESR (Erythrocyte Sedimentation Test): Blood test that checks for inflammation in the body.
- Urinalysis: Urine test that detects a range of conditions linked to Raynaud’s disease.
- Pulse volume recording: A type of non-invasive test that checks the blood flow in the arms and legs.
- RF (Rheumatoid Factor) test: Blood test that checks for autoimmune diseases.
Raynaud’s Disease Treatment
Depending on the cause, medicines can support Raynaud’s disease treatment. These medicines may include:
Medicines
- Calcium channel blockers: These drugs help relax and open small blood vessels in the hands and feet. They also help heal sores on the fingers and toes.
- Vasodilators: These drugs help relax blood vessels.
Surgery and Other Medical Procedures
- Nerve surgery: Nerves in the hands and feet control the opening and narrowing of blood vessels in the skin. Employed if Raynaud’s does not respond to medication, nerve surgery or sympathectomy destroys nerves triggering the narrowing of blood vessels. The surgery, if successful, can lead to fewer and shorter episodes.
- Chemical injections: Injections or shots of numbing medicine or onabotulinumtoxinA (botox) blocks nerves in affected hands or feet.
Possible Complications of Untreated Raynaud’s Disease
Raynaud’s Disease is often mild. But if it is not managed, repeated attacks can affect the tissues over time.
Here are the possible complications:
- Poor blood supply: Frequent narrowing of blood vessels reduces oxygen to the skin.
- Skin changes: Skin may become thin, tight, or shiny. Healing becomes slow.
- Pain and numbness: Repeated episodes can lead to ongoing discomfort or loss of sensation.
- Sores or ulcers: Lack of blood flow can cause painful open sores on fingers or toes.
- Infections: Open sores increase the risk of infection.
- Tissue damage (rare but serious): In severe cases, tissue can die due to very low blood supply. This is called Gangrene.
In simple terms, most people do fine. But severe or untreated cases can damage the skin and tissues due to lack of proper blood flow.
When to See a Doctor for Raynaud’s Syndrome Symptoms?
You should see a doctor if you notice symptoms of Raynaud’s Disease and they are not mild or occasional.
Here’s when it matters:
- Frequent attacks: If episodes happen often or are getting worse.
- Severe pain: If your fingers or toes hurt a lot during or after an attack.
- Sores or wounds: If you notice ulcers, cracks, or slow-healing wounds.
- Skin colour changes that last long: If white or blue colour does not return to normal quickly.
- Numbness or loss of feeling: If the sensation doesn’t come back fully.
- Only one side is affected: For example, symptoms in just one hand or a few fingers. This can suggest a more serious cause.
- Symptoms start later in life: If they begin after age 30–40, it may be secondary Raynaud’s.
- Signs of another illness: Such as joint pain, skin thickening, or fatigue. These may point to conditions like Scleroderma or Lupus.
In short, mild and occasional symptoms are common. But if they are severe, frequent, or unusual, it’s best to get checked early.
