In sickle cell disease, avascular necrosis (AVN) can occur due to the progressive impairment of blood supply to the bones caused by the sickling process. In AVN, the bone tissue dies and the bone collapses, as Johns Hopkins Medicine explains. The sickling process can also cause chronic anemia, blood…

A sickle cell crisis isn’t a polite guest, and it often arrives unannounced. Over the years, I’ve learned that my crises either come on suddenly or build gradually, with subtle clues or a red alert. Recognizing these warning signs of a sickle cell pain crisis early is the first…

As I look back on my two-year journey as a sickle cell disease columnist for Bionews, the parent company of this website, I’m struck by how much I’ve grown and evolved. In fact, I’m extremely proud. It all began in late 2022, when I stumbled upon a job posting…
Recently, I’ve been reflecting on how living with sickle cell disease has affected many of my dreams, goals, and lifestyle choices. Despite the changes, I have continued to dream and pursue my aspirations successfully. The impact of sickle cell disease intensified for me during…
A few weeks ago, I was in excruciating pain in the dead of the night. I’m not one to disturb others when I’m in pain unless it’s severe and I need help to manage it. This night was one of those exceptions, and I had to reluctantly wake up my…
Some of my childhood memories still linger. I vividly remember, for instance, the lonely nights spent in my bed while struggling with a painfully distended abdomen, a discomfort extreme enough to take away many nights of sleep. My bed was in the same room as my parents, yet I was…
Hydration plays a vital role in the management of sickle cell disease. It offers numerous benefits, including enhanced blood flow, and can help prevent or treat sickle cell crises and other disease complications. Sickle cell is a genetic disorder that alters the shape and structure of red blood cells.
Managing multiple sickle cell complications can be emotionally and physically overwhelming. Today I’d like to share an experience that still resonates deeply with me: my heartbreaking reaction to the diagnosis of one of those complications. Interestingly, it wasn’t the worst I’ve faced, but my reaction to it was undoubtedly…
With sickle cell disease, pain is often ever-present. Many people who have this disease experience various forms of pain throughout their lifetimes. Sometimes the pain is acute, other times it’s chronic, and still others it’s acute-on-chronic (when acute pain develops into chronic pain). Pain may be caused by various…
As last year drew to a close, a thought-provoking post in the Sickle Cell Celebs Facebook group inspired me to reflect on what I wish people understood about sickle cell disease. This introspection led me to come up with a long list that I’ve decided to share. There’s…
Sickle cell disease can manifest as both a visible and invisible illness, depending on the individual and their unique complications. For some, the symptoms are apparent, but for others, the disease remains largely hidden. Many sickle cell patients are prone to stigma and discrimination. When the disease is…
Blood transfusions play a critical role in the management of sickle cell disease. They can help prevent and manage various complications as well as reduce disease severity. This lifesaving intervention has brought many sickle cell patients on the verge of death back to life — including me. Despite being…
Living with sickle cell disease is not a proverbial bed of roses; instead, it’s a journey of twists and turns. Yet I’m grateful for the experience. It’s imparted invaluable life lessons that have shaped me into the woman I am today, and that woman is a better human being.
