Allergies

Altitude sickness
Altitude sickness, also known as acute mountain sickness (AMS), can occur when you ascend to high altitudes too quickly. Symptoms typically begin to appear at elevations above 2,500 metres (8,200 feet) and may include headaches, nausea, dizziness, fatigue, and difficulty sleeping. In more severe cases, it can lead to high altitude pulmonary oedema (HAPE) or high altitude cerebral oedema (HACE), both of which are serious conditions. To treat altitude sickness, the most effective approach is to descend to a lower altitude as soon as possible. Staying hydrated and resting can also help alleviate mild symptoms. Over-the-counter pain relievers may provide relief from headaches, while anti-nausea medications can assist with feelings of sickness. Preventing altitude sickness is mainly about acclimatisation. Gradually ascending to higher altitudes allows your body to adjust. It’s recommended to increase your altitude by no more than 300 to 500 metres (1,000 to 1,600 feet) per day, and to spend an extra day at higher altitudes if you start feeling unwell. Staying well-hydrated and avoiding alcohol can also reduce the risk of developing altitude sickness.
Cirrhosis
Cirrhosis is a condition characterised by severe liver scarring, which can result from various causes, including chronic alcohol abuse, viral hepatitis, and certain autoimmune diseases. The liver becomes damaged over time, leading to a decline in its ability to function properly. Symptoms of cirrhosis can vary greatly and may not appear until the disease is advanced. Common signs include fatigue, weakness, loss of appetite, nausea, and weight loss. As the condition progresses, individuals might experience more severe symptoms such as jaundice (yellowing of the skin and eyes), swelling in the legs and abdomen, and confusion or difficulty thinking clearly due to a buildup of toxins in the brain. Certain groups of people are at a higher risk of developing cirrhosis. This includes those with a history of heavy alcohol consumption, individuals infected with hepatitis B or C, and those with obesity or diabetes. Additionally, conditions like fatty liver disease and certain genetic disorders can also increase the likelihood of cirrhosis. Treatment for cirrhosis focuses on managing the underlying cause and preventing further liver damage. This may involve lifestyle changes, such as adopting a healthier diet, avoiding alcohol, and maintaining a healthy weight. In some cases, medications may be prescribed to manage symptoms or treat the underlying disease. If cirrhosis progresses to liver failure, a liver transplant may be necessary. Regular monitoring and check-ups with a healthcare professional are crucial for anyone at risk or diagnosed with cirrhosis.
Dengue
Dengue is a viral infection transmitted by mosquitoes. It is primarily found in tropical and subtropical regions around the world. Common symptoms include high fever, severe headaches, pain behind the eyes, joint and muscle pain, rash, and mild bleeding. If you experience these symptoms, especially after being in an area where dengue is prevalent, it's important to seek medical assistance. To reduce your risk of dengue, you can take preventive measures such as using mosquito repellent, wearing long sleeves and trousers, and ensuring your living environment is free from standing water where mosquitoes breed.
Hiatus hernia
A hiatus hernia occurs when a portion of your stomach pushes up through the diaphragm into the chest cavity. This condition can arise due to various factors, including age-related weakening of the diaphragm, obesity, pregnancy, or persistent coughing and straining. Symptoms may include heartburn, chest pain, and difficulty swallowing. If treatment is necessary, options can range from lifestyle changes, such as diet modifications and weight loss, to medications that reduce stomach acid. In some cases, surgery may be recommended to correct the hernia.
Japanese encephalitis
Japanese encephalitis is a viral infection that affects the brain and is primarily spread by mosquitoes. Those most at risk include individuals living in or travelling to rural areas of Asia, especially during the rainy season when mosquito populations are high. To reduce the risk of infection, it's important to take preventive measures such as using insect repellent, wearing long-sleeved clothing, and sleeping under mosquito nets. Vaccination is also recommended for people planning to spend extended periods in high-risk areas. Symptoms of Japanese encephalitis can range from mild to severe and may include fever, headache, neck stiffness, and confusion. In more severe cases, it can lead to seizures, paralysis, or even coma. Treatment primarily focuses on supportive care, as there is no specific antiviral treatment for the infection. This may involve hospitalisation for monitoring and managing symptoms. Early intervention is crucial for improving outcomes.
Kidney infection
Learn about kidney infection, known as pyelonephritis, which is a form of urinary tract infection. This condition can present various symptoms, including fever, chills, back or side pain, and painful urination. Treatment typically involves antibiotics to eliminate the infection, and in some cases, hospitalisation may be necessary for more severe infections. It’s important to seek medical attention if you experience persistent symptoms, severe pain, or notice blood in your urine, as prompt care can prevent complications.
Labyrinthitis and vestibular neuritis
Labyrinthitis and vestibular neuritis, sometimes referred to as vestibular neuronitis, are conditions that affect the inner ear and can cause balance issues. It's important to understand the symptoms of these conditions, know when to seek medical assistance, and be aware of the treatment options available. Labyrinthitis typically involves inflammation of the inner ear structures, leading to symptoms such as dizziness, hearing loss, and tinnitus (ringing in the ears). Vestibular neuritis, on the other hand, primarily affects the vestibular nerve, resulting in severe dizziness or vertigo, but usually does not involve hearing loss. If you experience sudden, severe dizziness, difficulty maintaining balance, or persistent ear-related symptoms, it's advisable to consult a healthcare professional. These symptoms can significantly impact your daily life and may require specific medical evaluation. Treatment for both conditions may include medications to alleviate symptoms such as nausea and dizziness, as well as vestibular rehabilitation therapy to help restore balance. In some cases, addressing the underlying cause, such as an infection, may also be necessary. Always seek guidance from your doctor for the best course of action tailored to your individual needs.
