When to seek medical help
If your a headache is severe, sudden, or accompanied by other concerning symptoms, seek urgent medical attention. Always consult a healthcare professional if you are concerned.
Conditions related to a headache
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.
Brain aneurysm
A brain aneurysm is a bulge in a blood vessel in the brain that can occur when the vessel wall weakens. Symptoms of a brain aneurysm can vary; some people may not experience any symptoms at all, while others might have headaches, vision problems, or difficulty speaking. If you notice sudden and severe headaches, changes in vision, or any unusual neurological symptoms, it’s crucial to seek medical attention immediately. Treatment for a brain aneurysm often depends on its size, location, and whether it has ruptured. Options may include monitoring the aneurysm, surgical procedures to clip or coil it, or other interventions to prevent a rupture. To reduce the risk of an aneurysm bursting, it’s advisable to manage blood pressure, avoid smoking, maintain a healthy lifestyle, and follow a balanced diet. Regular check-ups with your healthcare provider can also help monitor your risk factors.
Carbon monoxide poisoning
Carbon monoxide poisoning occurs when carbon monoxide (CO), a colourless and odourless gas, is inhaled, leading to harmful effects on the body. Common symptoms include headaches, dizziness, shortness of breath, nausea, confusion, and fatigue. In severe cases, it can lead to loss of consciousness or even death. If you suspect carbon monoxide poisoning, it’s crucial to get fresh air immediately. Leave the area and call for emergency medical help. Do not re-enter the space until it has been properly ventilated and checked for CO levels. The primary cause of carbon monoxide poisoning is the incomplete burning of fuels, which can occur in appliances such as gas boilers, stoves, or fireplaces. Other sources include car exhaust fumes and generators used indoors. Treatment typically involves administering oxygen to the affected person, which helps to remove carbon monoxide from the bloodstream. In severe cases, hyperbaric oxygen therapy may be necessary. To prevent carbon monoxide poisoning, ensure that all fuel-burning appliances are well-maintained and properly ventilated. Installing a carbon monoxide detector in your home can provide an early warning of dangerous levels of the gas. Regularly check and replace batteries in the detector to ensure it functions correctly.
Chest infection
Learn about chest infections, including their symptoms, self-care measures, and how a pharmacist or GP can assist you. Typically, a chest infection will resolve on its own within 7 to 10 days.
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.
Glaucoma
Glaucoma is a group of eye conditions that can lead to damage of the optic nerve, often due to high pressure within the eye. It is important to be aware of the symptoms, types, causes, diagnostic methods, and available treatments and support for this condition. Symptoms of glaucoma can vary, but many people may not experience noticeable signs in the early stages. Common symptoms include gradual loss of peripheral vision, difficulty seeing in low light, and seeing halos around lights. In acute cases, individuals may experience sudden eye pain, headache, nausea, and blurred vision. There are several types of glaucoma. The most common is primary open-angle glaucoma, which develops slowly and without obvious symptoms initially. Angle-closure glaucoma occurs when the drainage angle of the eye becomes blocked, leading to a rapid increase in eye pressure. Other types include normal-tension glaucoma, where optic nerve damage occurs without high eye pressure, and congenital glaucoma, which is present at birth. The causes of glaucoma can vary. Increased eye pressure is a major risk factor, often resulting from an imbalance in the production and drainage of fluid within the eye. Other risk factors include age, family history of glaucoma, certain medical conditions such as diabetes, and prolonged use of corticosteroid medications. To diagnose glaucoma, an eye care professional will conduct a comprehensive eye examination, which may include measuring intraocular pressure, assessing the optic nerve, testing peripheral vision, and performing imaging tests to evaluate the optic nerve and retina. Treatment options for glaucoma aim to lower eye pressure and prevent further damage to the optic nerve. Common treatments include prescription eye drops, oral medications, laser therapy, and surgical procedures. Regular check-ups and monitoring are essential to manage the condition effectively. Support is also available for those living with glaucoma, including educational resources, support groups, and counselling services to help individuals cope with the emotional and practical aspects of the condition.
Haemophilus influenzae type b (Hib)
Haemophilus influenzae type b (Hib) is a type of bacteria that can lead to serious infections, particularly in young children. It is known to cause a variety of illnesses, including meningitis, pneumonia, and epiglottitis, which is an inflammation of the throat that can obstruct breathing. Symptoms of Hib infections can vary depending on the type of illness but may include high fever, headache, stiff neck, difficulty breathing, and a sore throat. The bacteria are typically spread through respiratory droplets when an infected person coughs or sneezes. While Hib was once a common cause of severe illness in children, the introduction of the Hib vaccine has significantly reduced the incidence of these infections. Vaccination is the best way to prevent Hib disease. The Hib vaccine is usually given to infants as part of their routine immunisations, typically at two, four, and twelve to fifteen months of age. This vaccine has proven to be highly effective in protecting against infections caused by Hib.
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.
