Diseases starting with w

  • 10

    Waldenstrom’s macroglobulinaemia

    Waldenstrom’s macroglobulinaemia is a rare, slow-growing blood cancer that affects white blood cells and causes production of an abnormal protein that can thicken the blood, making it harder to flow through blood vessels.

  • 2

    Waldenstrom’s macroglobulinaemia recurrent

    Waldenstrom’s macroglobulinaemia is a rare blood cancer that cannot be completely cured, which means that after successful treatment, the disease will eventually return. Understanding what happens when the cancer comes back and knowing your treatment options can help you manage this condition effectively.

  • 4

    Waldenstrom’s macroglobulinaemia refractory

    When Waldenstrom’s macroglobulinemia comes back after treatment or stops responding to therapy, patients and their healthcare teams face new decisions about the best path forward.

  • 3

    Warm autoimmune haemolytic anaemia

    Warm autoimmune haemolytic anaemia is a rare condition where the body’s immune system mistakenly attacks and destroys its own red blood cells, leading to profound fatigue and other serious symptoms that can severely impact daily life.

  • 2

    Weaning failure

    Between 20% and 30% of patients requiring mechanical ventilation face significant challenges when doctors try to remove their breathing support, a condition known as weaning failure. Understanding why this happens and how to address it can make a crucial difference in recovery.

  • 5

    Wheezing

    Wheezing is a high-pitched whistling or rattling sound you hear when breathing, usually when air struggles to pass through narrowed or partially blocked airways. It can be a temporary reaction to a cold or allergies, or it may signal a more serious health condition that requires medical attention.

  • 2

    White matter lesion

    White matter lesions appear as bright spots on brain scans and signal areas where the brain’s communication pathways have been damaged. While some lesions are a normal part of aging and cause no symptoms, others can lead to memory problems, balance difficulties, and changes in mood.

  • 2

    Wiskott-Aldrich syndrome

    Wiskott-Aldrich syndrome is a rare genetic condition that disrupts the immune system, causes dangerous bleeding problems, and leads to persistent eczema. Without proper treatment, this inherited disorder can become life-threatening, but modern medical advances offer hope through stem cell transplantation and gene therapy.

  • 2

    Wolfram syndrome

    Wolfram syndrome is a rare genetic condition that damages multiple body systems over time, usually beginning with diabetes and vision problems in childhood and progressing to affect the brain and other organs.
