Family traits handed down to us and DNA play a large role in our health and well-being. Genetic changes and traits carried by parents may appear in their children, even though the parents don’t have any physical characteristics of those conditions. Some of these conditions are more common than others. Heart disease, high cholesterol and type 2 diabetes are a few examples.

Some diseases affect the blood. One group of blood disorders is called sickle cell disease (SCD). It damages red blood cells by changing the shape. Healthy red blood cells are a flexible disc shape. Their shape allows them to move easily through the body. With SDC, red blood cells become stiff, sickle-shape cells that block blood flow, which causes pain and organ damage.

The National Heart, Lung, and Blood Institute reveals individuals with SCD also have abnormal hemoglobin (hemoglobin S) – a protein that helps our bodies use oxygen.

When someone has SCD, it means they’ve inherited two abnormal hemoglobin genes – one from each parent. Despite widespread misconceptions that SCD is only found in the Black community, SCD can actually affect anyone of any race or ethnicity.  

Sickle Cell Symptoms

Fortunately, modern medicine can now identify SCD before it begins to complicate a child’s daily life. When a child is born with SCD, parents will know long before symptoms start to show (at around five to six months of age). In the United States, it is required that all newborns receive screening for SCD. Some children may experience problems early on while others won’t have problems until later in life.

Early symptoms include:

• Painful swelling of the hands and feet
• Fatigue or fussiness from low iron in the blood
• Yellowing of the skin or of the whites of the eyes

As every person is different, symptoms may be different for each person and change over time. Most of the visible signs of SCD are related to complications.

Sickle Cell Complications

Pain can occur in people with SCD when the delivery of oxygen throughout the body is blocked. They may experience crisis pain – pain that lasts for several hours or even several days. This happens when sickled cells block small blood vessels that carry blood to the bones. The pain is described as sharp, intense, stabbing or throbbing. Individuals who experience a pain crisis can be hospitalized for several days. The pain can affect any part of the body and more than one area at a time. The pain often occurs in the:

• Lower back
• Legs
• Arms
• Abdomen
• Chest

Along with crisis pain, individuals with SCD can suffer from other complications, including:

• Chronic pain: The cause of chronic pain is not well understood and is usually different from crisis pain. Patients have stated that the pain is hard to describe.
• Severe anemia: People with SCD typically have mild to moderate anemia, however severe, life-threatening anemia can also develop.
• Infections: Sickle cell can damage the spleen, the organ that protects the body against certain types of germs. Individuals with a damaged spleen are at risk for serious, life-threatening bacterial infections. These infections can morph into blood, lung, brain, spinal cord or bone infections.
• Acute chest syndrome: SCD can deprive the lungs of oxygen. When this happens, it can damage lung tissue and cause chest pain and difficulty breathing.
• Jaundice or icterus: The skin and whites of the eyes take on a yellowish color when a large number of red blood cells rupture.

Living with Sickle Cell Disease

Education and understanding are always important first steps when living with any kind of chronic illness. If you or your child has SCD, learn as much as possible. Build a relationship with your doctor so you feel comfortable asking questions. Developing a plan to manage your disease and complications can also help.

Babies and children with SCD should be seen by a doctor with experience caring for patients with the disease. Seeing a hematologist, or blood disease specialist, may also be a care option. People living with SCD should see their care provider regularly – every three to 12 months for preventive measures.

Pursue a Healthy Lifestyle

As with many other conditions, maintaining a healthy lifestyle can help limit complications. Strengthen your body with:

• A nourishing diet
• Plenty of sleep
• Regular physical activity

Limit activities that can harm your health. Stop smoking. Drink alcohol in moderation. Steer clear of situations that can trigger a pain crisis. Take time to rest. Drink plenty of water to stay hydrated, and avoid extreme heat or cold.
