Brain abscess
A brain abscess is a pus-filled mass located within the brain. This condition is uncommon and can be life-threatening, typically resulting from an infection or a serious head injury.
Chronic kidney disease
Chronic kidney disease (CKD) is a long-term condition where the kidneys gradually lose their ability to function effectively. This decline in kidney function can lead to a build-up of waste products in the body, which can be harmful. Symptoms of CKD can be quite subtle in the early stages and may include fatigue, swollen ankles, changes in urination frequency, and high blood pressure. As the condition progresses, individuals might experience more severe symptoms such as nausea, shortness of breath, and a reduced appetite. Diagnosis of CKD typically involves blood tests to measure kidney function, as well as urine tests to check for protein or blood. Imaging tests like ultrasounds may also be used to assess the kidneys' structure. Treatment for CKD focuses on managing symptoms and slowing the progression of the disease. This can involve lifestyle changes such as adopting a healthy diet, controlling blood pressure, and managing diabetes if applicable. In more advanced cases, medications may be prescribed, and some individuals might eventually require dialysis or a kidney transplant.
Cluster headaches
Cluster headaches are intense episodes of pain that typically occur on one side of the head. These headaches are known for their excruciating nature and can be accompanied by other symptoms. It's important to recognise when to seek medical attention, as well as understanding the available treatment options.
Clostridioides difficile (C. diff) infection
Learn about Clostridioides difficile, commonly referred to as C. difficile or C. diff. This bacterium can lead to a range of symptoms, primarily affecting the digestive system. Key symptoms include severe diarrhoea, abdominal pain, fever, and nausea. Certain groups of people are at a higher risk of infection, particularly those who have recently taken antibiotics, the elderly, and individuals with weakened immune systems. Treatment typically involves antibiotics specifically designed to combat C. difficile, and in more severe cases, additional interventions may be necessary to manage complications.
Cyclospora
Cyclospora is a type of parasite that can cause an intestinal infection known as cyclosporiasis. This infection is typically contracted by consuming food or water contaminated with the parasite's spores. It is often associated with fresh produce, such as berries, salad greens, and herbs, especially if they have been contaminated during growing or harvesting. Cyclospora is commonly found in tropical and subtropical regions, but cases have been reported in various parts of the world, including the UK, particularly when food is imported from affected areas. Symptoms of cyclosporiasis usually appear about one week after infection and can include watery diarrhoea, stomach cramps, nausea, fatigue, and loss of appetite. Some people may also experience weight loss and bloating. The symptoms can persist for several weeks if not treated, making it important to seek medical advice if you suspect you have been infected.
