Sickle Cell Crisis:
What Everyone Should Know
For millions of people and their families, a sickle cell crisis is not a medical textbook term — it is a lived, often frightening reality. Understanding what it is, what causes it, and how to respond can make a genuine difference.
What Is Sickle Cell Disease?
Sickle cell disease (SCD) is an inherited blood disorder passed down through families. In a healthy body, red blood cells are round, flexible, and flow smoothly through blood vessels, carrying oxygen to every part of the body. In sickle cell disease, a gene mutation causes these cells to become rigid, sticky, and crescent — or "sickle" — shaped.
These abnormal cells can clump together, blocking blood flow and starving tissues of oxygen. They also break down faster than healthy red blood cells, leading to chronic anaemia. SCD affects approximately one in every 500 African American births and is also prevalent across sub-Saharan Africa, the Middle East, the Mediterranean, and India. In Nigeria alone, tens of thousands of babies are born with SCD every year.
"Sickle cell disease is not rare — it is one of the most common inherited disorders in the world, yet it remains one of the most underserved."
So, What Is a Sickle Cell Crisis?
The term sickle cell crisis describes a group of acute, often sudden medical events that occur in people living with SCD. These episodes signal that the disease has entered an active, dangerous phase — and prompt recognition is everything.
There are several distinct types of sickle cell crisis, and understanding them helps patients, caregivers, and the wider community know what to watch for and when to act.
Vaso-Occlusive Crisis
The most common type. Sickled cells block small blood vessels, causing severe pain — most often in the bones, back, chest, or joints. Also called an "acute painful crisis."
Acute Chest Syndrome
A serious lung complication involving chest pain, fever, and difficulty breathing. It is a leading cause of death in SCD and requires urgent hospital care.
Aplastic Crisis
The bone marrow temporarily stops producing red blood cells, causing a sudden, severe drop in haemoglobin. Often triggered by parvovirus B19 infection.
Splenic Sequestration
Large amounts of blood suddenly pool in the spleen, causing it to enlarge rapidly and the blood pressure to drop dangerously. Most common in young children.
Hyperhemolytic Crisis
An accelerated breakdown of red blood cells leading to worsening anaemia and jaundice. Can be triggered by certain medications or infections.
Dactylitis
Painful swelling of the hands and feet due to blocked blood flow in small bones. It is often the very first sign of SCD in young babies and toddlers.
What Triggers a Sickle Cell Crisis?
Crises do not always announce themselves with clear warning. However, certain conditions are well known to set them off. Recognising these triggers — and avoiding them where possible — is one of the most powerful tools a person with SCD has.
Common Sickle Cell Crisis Triggers
- Dehydration — even mild fluid loss can cause sickling
- Infections — bacterial or viral illness, including the common cold
- Extreme temperatures — exposure to cold or sudden temperature changes
- Physical overexertion or intense exercise without proper rest
- Emotional stress and anxiety
- High altitudes or low oxygen environments
- Alcohol and smoking
- Skipping medications, particularly hydroxyurea
Recognising the Warning Signs
A crisis can develop gradually over hours or arrive with sudden, alarming intensity. Learning the early signs — and acting on them quickly — can reduce severity and potentially prevent hospitalisation.
Signs That a Crisis May Be Starting
- Sudden or escalating pain anywhere in the body
- Chest pain or tightness
- Shortness of breath
- Fever above 38.5°C (101.3°F)
- Extreme fatigue or pallor
- Rapid breathing
- Sudden swelling of hands or feet
- Yellowing of the skin or eyes (jaundice)
- Persistent headache or vision changes
- Abdominal or side pain
If any of the above are accompanied by fever, difficulty breathing, or sudden severe pain — seek emergency care immediately. Acute chest syndrome and stroke, in particular, are life-threatening emergencies that cannot wait.

Managing a Sickle Cell Crisis
For mild to moderate episodes, some people are able to manage at home. The goals are to relieve pain, stay hydrated, and prevent the crisis from worsening. However, home management should always be part of a care plan agreed with a doctor or pharmacist — not improvised.
At-Home Measures
Keeping warm, drinking plenty of fluids (water, not alcohol), and taking prescribed pain relief as directed are the cornerstones of early crisis management. Oral analgesics such as paracetamol and ibuprofen are commonly used for mild pain, while stronger opioid medications may be prescribed for more severe episodes. Applying a warm compress — never ice — to painful areas can also help.
When to Go to Hospital
Any fever, difficulty breathing, sudden worsening of pain, or neurological symptoms (confusion, slurred speech, weakness on one side) means going straight to the emergency department. Do not wait to see if it improves on its own.
Living With Sickle Cell Disease: Prevention Is Power
While a cure remains out of reach for most patients — though gene therapies like Casgevy are offering hope — the day-to-day management of SCD focuses on reducing the frequency and severity of crises. This is where long-term care planning, consistent medication, and access to reliable health support become life-changing.
Everyday Strategies to Reduce Crisis Risk
- Stay well-hydrated throughout the day, every day
- Take hydroxyurea or other prescribed medications consistently
- Keep all vaccinations and annual flu shots up to date
- Dress appropriately for cold weather; avoid temperature extremes
- Practice stress management and adequate rest
- Attend regular check-ups with your haematologist or SCD clinic
- Carry an emergency care plan and medication list at all times
- Folic acid supplementation — speak to your pharmacist about dosage
The Role of Your Pharmacist
Many people living with SCD are used to navigating their condition largely alone — especially outside of clinic hours. A community pharmacist is one of the most accessible healthcare professionals you have, and one of the most underused.
Your pharmacist can help you understand your medications and their interactions, advise on pain management options, flag when your symptoms need escalation to emergency care, ensure your repeat prescriptions are on time, and provide honest, knowledgeable guidance whenever you need it — not just during clinic hours.

A Word on Sickle Cell Awareness
June 19th is World Sickle Cell Day — a global moment to educate, advocate, and stand alongside those living with this condition. But awareness should not be a once-a-year event. Sickle cell disease affects communities across Nigeria, Ghana, the UK, the United States, and beyond. It is not rare. It is not distant. It may be affecting someone you know, love, or live with right now.
The more communities understand this disease — its triggers, its warning signs, and the importance of timely care — the fewer lives it claims unnecessarily. Share this article. Talk about it. And if you or someone you care for lives with SCD, know that support is closer than you think.
