Asthma is a common, long-term condition that affects the lungs and typically starts in childhood. It is an inflammation of the small tubes in your airway called bronchi. It can be triggered, and asthma attacks can be caused by dust mites, animal fur, pollen, exercise, smoke and viral infections. You are more likely to develop asthma if you have a family history of the condition. Many professional athletes have asthma and it does not prevent them from participating in sport, they will just need to ensure they manage their condition to reduce risks of an asthma attack.

Diabetes is a serious condition that is linked to an individual’s blood sugar levels. When we eat or drink, some of the food is converted in glucose which the body uses for energy. Insulin will control the levels of glucose used for energy but this system does not work effectively if you suffer from diabetes which can lead to hypoglycaemia (extreme low blood sugar levels) and hyperglycaemia (extreme high blood sugar levels). There are two types of diabetes; Type 1 and Type 2. 

Epilepsy can start at any age, but it most often begins during childhood. It's often not possible to identify a specific reason why someone develops the condition, although some cases, particularly those that occur later in life, are associated with damage to the brain. Epilepsy is referred to as abnormal or unusual brain activity resulting in unprovoked seizures. Some cases of epilepsy may be caused by changes in the brain that occur as a result of the genes you inherit from your parents. There are two main types of seizure that can occur; tonic-clonic seizures (this is the one that you will instantly think of) and focal seizures. A tonic-clonic seizure will typically result in an individual losing consciousness, falling to the ground and have uncontrollable convulsions. A focal seizure can occur without knowledge of it happening. Blank staring or 'day dreaming' can be signs that someone has suffered a focal seizure.
