Understanding Sickle Cell Anemia

By: Alyza Kour



Sickle Cell Anemia is a serious inherited blood disorder that affects millions of people around the world. It is a type of Sickle Cell Disease in which red blood cells become hard, sticky, and shaped like crescent moons or “sickles.” These abnormal blood cells do not move through blood vessels as easily as healthy, round blood cells, which can lead to pain, fatigue, and other health complications.

Sickle Cell Anemia is caused by a genetic mutation that affects hemoglobin, the protein in red blood cells that carries oxygen throughout the body. A person is born with the disease when they inherit the sickle cell gene from both parents. Because the condition is inherited, it cannot spread from person to person like a virus or infection.

The disease affects the body in several ways. Sickled blood cells can block blood flow and reduce oxygen reaching organs and tissues. These cells also break apart more quickly than normal red blood cells, which causes anemia. Over time, Sickle Cell Anemia can damage important organs such as the lungs, kidneys, heart, and brain. Many people with the condition experience painful episodes called pain crises, which may require hospitalization.

Common symptoms of Sickle Cell Anemia include severe pain, tiredness, swelling in the hands and feet, dizziness, shortness of breath, jaundice, and frequent infections. Symptoms often begin during early childhood and can vary from person to person.

Doctors diagnose Sickle Cell Anemia using blood tests, including newborn screening tests that are commonly performed shortly after birth. Genetic testing and hemoglobin tests can also help confirm the diagnosis. Early detection is important because it allows patients to begin treatment and monitoring as soon as possible.

Although there is not yet a universal cure for everyone with Sickle Cell Anemia, treatments can help manage symptoms and improve quality of life. Common treatments include pain medication, antibiotics, blood transfusions, and medicines such as Hydroxyurea that help reduce pain crises. Some patients may also qualify for stem cell or bone marrow transplants.

Living with Sickle Cell Anemia can be difficult, especially during pain crises or periods of fatigue. Many people with the condition need regular medical care and must stay hydrated, avoid extreme temperatures, and manage stress carefully. Even with these challenges, many individuals with Sickle Cell Anemia live active, meaningful, and successful lives with the help of proper treatment and support systems.

Understanding Cystic Fibrosis

Blog written by Alyza Kour - Reasearch Lead of Teen Med Spot   Mucus in our body is more than just “gross stuff” coming out our nose when we have a cold, it’s actually a vital protective layer. Its job is to line our lungs, digestive tract, and other organs to keep them moist and to trap dust, bacteria, or virusese so your body can get rid of them. Healthy mucus is thin, slippery, and water (Think of it like a layer of liquid soap). ( Cleveland Clinic ) What is cystic fibrosis? It is a genetic disease that causes sticky, thick mucus to build up in your organs (Lungs, Digestive System, Pancreas), blocking and damaging them. ( Cleveland Clinic.org ) What causes cystic fibrosis? Changes to the CFTR gene - called variants or mutations - cause cystic fibrosis. CFTR makes a protein that works as an ion channel on the surface of a cell. Ion channels are like gates in a cell’s membrane that allow certain molecules to pass through. Think of this protein as a “gate” for chloride ions (sa...

Uncovering the Clinical Characterization and Mechanisms of Fibrodysplasia Ossificans Progressiva (FOP) By: Sharen Rego

Image
 Introduction Fibrodysplasia Ossificans Progressiva or FOP is an exceedingly rare, yet severely disabling genetic disorder, characterized by the abnormal formation of bone tissue outside of the normal human skeleton (heterotopic ossification). This can occur within soft tissues like the skeletal muscles, tendons, and ligaments. With an estimated one in two million people affected globally, FOP represents one of the most complex genetic conditions known to modern medicine. Raising awareness for this disorder is crucial, as early symptoms are often misdiagnosed as cancer, leading to harmful medical interventions like biopsies or routine muscle injections which trigger irreversible bone growth. Main Body At the cellular level, FOP is caused by a specific mutation in the ACVR1 gene located on chromosome 2. This gene provides instructions for making a specialized receptor protein that controls when and where the body builds bone tissue (such as during fetal development or when healing a...

Understanding: Pompe Disease

Understanding: Pompe Disease   (Written April 11th, 2026) Blog written by Alyza Kour - Research Lead of Teen Med Spot,   Pompe Disease: CONTEXT : Glycogen is a highly branched polysaccharide that acts as the primary, short-term storage form of glucose in animals and humans. Stored mainly in the liver and muscles, and it is broken down into glucose for quick energy during exercise or fasting. It acts as a “buffer” for blood sugar levels. ( Cleveland Clinic.org ) NOTE : There are 3 types of Pompe Disease: - Classic Infantile-Onset Pompe Disease, (Rapid progression, severe heart/muscle issues, appearing within the first few months of life) - Non-Classic Infantile-Onset Pompe Disease, (Slower, delayed motor skills, usually appearing by age 1) - Late-Onset Pompe Disease, (Progressive muscle/breathing weakness, symptoms can begin in childhood, adolescence, or adulthood) - ( MedlinePlus.gov / National Organization for Rare Disorders ) What is Pompe Disease? - A rare, inherited metab...
