Gastroesophageal reflux (GER) happens when acid from the stomach flows up into the tube that connects the mouth and the stomach (esophagus). Normally, food travels down the esophagus and stays in the stomach to be digested. However, when a person has GER, food and stomach acid sometimes move back up into the esophagus.
Antibiotic medicines are used to treat infections caused by bacteria, such as strep throat and urinary tract infection (UTI). Antibiotic medicines will not work for viral illnesses, such as colds or the flu (influenza). They work by killing the bacteria that is making you sick. Antibiotics can also have serious side effects. It is important that you take antibiotic medicines safely and only when needed.
Crohn's disease is a long-lasting (chronic) disease that affects the gastrointestinal (GI) tract. Crohn's disease often causes irritation and inflammation in the small intestine and the beginning of the large intestine, but it can affect any part of the GI tract. Crohn's disease is part of a group of illnesses that are known as inflammatory bowel disease (IBD).
Crohn's disease may start slowly and get worse over time. Symptoms may come and go. They may also go away for months or even years at a time (remission).
Lung cancer is an abnormal growth of cancerous cells that forms a mass (malignant tumour) in a lung. There are several types of lung cancer. The types are based on the appearance of the tumour cells. The two most common types are:
- Non-small cell lung cancer. This type of lung cancer is the most common type. Non-small cell lung cancers include squamous cell carcinoma, adenocarcinoma, and large cell carcinoma.
- Small cell lung cancer. In this type of lung cancer, abnormal cells are smaller than those of non-small cell lung cancer. Small cell lung cancer gets worse (progresses) faster than non-small cell lung cancer.
AIDS (acquired immunodeficiency syndrome) occurs when your body's disease-fighting system (immune system) is badly damaged and no longer protects you from infections and other health problems. This condition is caused by HIV (human immunodeficiency virus) infection.
Although your immune system is weakened when you are living with AIDS, your healthcare provider will give you instructions about how to stay as healthy as possible.
Epilepsy is a condition in which a person has repeated seizures over time. A seizure is a sudden burst of abnormal electrical and chemical activity in the brain. Seizures can cause a change in attention, behaviour, or the ability to remain awake and alert (altered mental status).
Carpal tunnel syndrome is a condition that causes pain, numbness, and weakness in the wrist, hand, and fingers. The carpal tunnel is a narrow, hollow space in the wrist. Tendons and one of the main nerves in the hand (median nerve) pass through the carpal tunnel. The median nerve supplies feeling to the thumb and the first three fingers. It also supplies the muscles at the base of the thumb. Carpal tunnel syndrome happens when the median nerve gets squeezed in the area where it passes through the carpal tunnel.
In some cases, it may not be possible to prevent carpal tunnel syndrome. However, you can take steps to relieve pressure on your wrist and reduce your risk of developing this condition.
Down syndrome is a genetic disorder that is caused by the presence of an extra chromosome at birth. A chromosome is the cell structure that contains genetic information. A person with Down syndrome is born with part or all of an additional copy of chromosome number 21. Down syndrome may cause certain physical characteristics, affect physical and mental development, and cause other health problems. However, your child can still lead a very active, successful, and happy life.
Alzheimer's disease is a brain disease that affects memory, thinking, language, and behaviour. People with Alzheimer's disease lose mental abilities, and the disease gets worse over time. Alzheimer's disease is a form of dementia.
