Conditions related to loss of appetite
Acute cholecystitis
Acute cholecystitis refers to the inflammation of the gallbladder, commonly triggered by a gallstone obstructing the cystic duct.
Alcohol-related liver disease
Alcohol-related liver disease (ARLD) is a condition that results from excessive alcohol consumption leading to liver damage. It can progress through various stages of severity and presents a variety of symptoms.
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.
Brucellosis
Brucellosis is an infectious disease caused by bacteria from the Brucella genus, often linked to livestock. It can be contracted through direct contact with infected animals or by consuming unpasteurised dairy products. Symptoms of brucellosis can vary but typically include fever, sweats, fatigue, headaches, muscle pain, and joint pain. Some individuals may also experience gastrointestinal issues like nausea and vomiting. If you suspect you have brucellosis, it’s essential to seek medical advice promptly. Your doctor may recommend blood tests to confirm the diagnosis. Treatment usually involves a course of antibiotics, which may last several weeks. It's crucial to complete the entire prescribed course to ensure the infection is fully eradicated. Early treatment can help prevent complications and improve recovery time.

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.
Cyclical vomiting syndrome
Cyclical vomiting syndrome (CVS) is a disorder characterised by recurrent episodes of severe vomiting that can last for hours or even days. The symptoms typically include intense nausea, vomiting multiple times an hour, abdominal pain, and sometimes other symptoms like headaches or dizziness. The exact cause of CVS is not fully understood, but it may be linked to genetic factors, migraines, or stress. Certain triggers, such as specific foods, infections, or emotional stress, can provoke episodes in some individuals. Diagnosis of CVS often involves ruling out other conditions that could cause similar symptoms. This may include medical history reviews, physical examinations, and various tests to exclude other gastrointestinal or metabolic disorders. Treatment for CVS focuses on managing symptoms and preventing future episodes. This can include medications to control nausea and vomiting, lifestyle changes, and identifying and avoiding triggers. Support from healthcare professionals, including dietitians and mental health specialists, can also be beneficial for those affected by the condition.
Flu
Flu, or influenza, is a viral infection that affects the respiratory system. Common symptoms of flu include a high fever, chills, muscle aches, fatigue, sore throat, runny or stuffy nose, and cough. Some individuals may also experience headaches and gastrointestinal issues, such as nausea or diarrhoea. For self-care, it’s important to rest and stay hydrated. Over-the-counter medications can help relieve symptoms like fever and aches. Be sure to use paracetamol or ibuprofen as directed on the packaging. Staying warm and drinking plenty of fluids can also aid recovery. You should seek medical assistance if you experience severe symptoms, such as difficulty breathing, chest pain, confusion, or if your symptoms worsen or do not improve after a few days. Vulnerable groups, including elderly individuals, young children, and those with underlying health conditions, should consult a healthcare professional promptly if they suspect they have the flu.
Granulomatosis with polyangiitis (GPA)
Granulomatosis with polyangiitis (GPA) is a rare autoimmune condition that causes inflammation of blood vessels, affecting various organs, particularly the lungs, kidneys, and sinuses. Symptoms can vary widely but often include persistent nasal congestion, sinus pain, cough, shortness of breath, fatigue, fever, and kidney issues such as blood in the urine. Diagnosis typically involves a combination of clinical evaluation, blood tests to check for specific antibodies, and imaging studies such as X-rays or CT scans. A biopsy of affected tissue may also be necessary to confirm the presence of granulomas, which are clusters of immune cells characteristic of the disease. Treatment usually involves medications to suppress the immune system and reduce inflammation. This often includes corticosteroids and other immunosuppressants. Early diagnosis and treatment are crucial to manage symptoms effectively and prevent serious complications. Regular follow-ups with healthcare providers are important to monitor the condition and adjust treatment as needed.
Hyperparathyroidism
Hyperparathyroidism is a condition where the parathyroid glands produce too much parathyroid hormone (PTH). This can lead to elevated levels of calcium in the blood, which may result in various symptoms. Common signs include fatigue, weakness, kidney stones, bone pain, and increased thirst or urination. There are two main types of hyperparathyroidism: primary and secondary. Primary hyperparathyroidism is often caused by a benign tumour on one of the parathyroid glands, while secondary hyperparathyroidism usually occurs in response to low calcium levels, often due to kidney disease. Treatment options depend on the severity of the condition and the symptoms present. In cases of primary hyperparathyroidism, surgical removal of the affected gland(s) is often recommended. For secondary hyperparathyroidism, managing the underlying cause, such as improving kidney function, may help. Additionally, medications may be prescribed to help control calcium levels or manage symptoms. It's important to consult with a healthcare professional for a proper diagnosis and to discuss the most suitable treatment plan.
Hepatitis C
Hepatitis C is a viral infection that affects the liver, potentially causing significant damage. It's important to understand the symptoms, causes, and available treatments for this condition.
