Dizziness
Dizziness can be linked to a range of health issues. It's important to speak with a healthcare professional if you encounter this symptom.
When to seek medical help
If your dizziness 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 dizziness
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.
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.
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.
Erythrocytosis
Erythrocytosis, also known as polycythaemia, refers to a condition characterised by an elevated level of red blood cells in the bloodstream. It's important to understand the symptoms associated with this blood disorder and the available treatment options.
Heart block
Heart block is a condition where the electrical signals in the heart are disrupted, affecting its ability to beat normally. Symptoms can vary but often include fatigue, dizziness, fainting, and in some cases, chest pain. There are several causes of heart block, including coronary artery disease, heart surgery, certain medications, and conditions that affect the heart muscle, such as myocarditis or cardiomyopathy. Heart block is classified into three main types: first-degree, second-degree, and third-degree (also known as complete heart block). First-degree heart block is the mildest form, where signals are delayed but still reach the heart's chambers. Second-degree heart block has two subtypes, with some signals failing to reach the heart, leading to skipped beats. Third-degree heart block is the most severe, where no signals reach the heart, causing it to beat independently and often too slowly. Diagnosis typically involves an electrocardiogram (ECG), which records the heart's electrical activity, along with other tests such as Holter monitoring or an exercise stress test to assess the heart's function over time. Treatment options depend on the severity and type of heart block. Mild cases may not require treatment, while more serious cases could necessitate the use of a pacemaker, a device that helps regulate the heart's rhythm. Support may also include lifestyle changes, medication management, and regular monitoring by a healthcare professional to manage symptoms and reduce risks.
Heat exhaustion and heatstroke
Heat exhaustion and heatstroke occur when your body overheats, and both can be quite serious. These conditions typically arise during a heatwave or in hot climates, but they can also result from engaging in very strenuous exercise.
