Intolerance
Intolerance
Intolerance (/ɪnˈtɒlərəns/) is a term used in the medical field to describe a condition where the body reacts negatively to certain substances, foods, or environmental factors. It is often confused with allergy, but the two are distinct in their causes and symptoms.
Etymology
The term "intolerance" comes from the Latin intolerantia, meaning "inability to bear or endure".
Types of Intolerance
There are several types of intolerance, including:
- Food intolerance: This is a digestive system response where a person has difficulty digesting certain foods.
- Lactose intolerance: This is a common type of food intolerance where a person has difficulty digesting lactose, a type of sugar found in milk and dairy products.
- Gluten intolerance: Also known as non-celiac gluten sensitivity, this is a condition where a person reacts negatively to the consumption of gluten, a protein found in wheat, barley, and rye.
- Drug intolerance: This is a condition where a person experiences side effects or adverse reactions when taking a drug at doses generally tolerated by others.
- Environmental intolerance: This is a condition where a person has a negative reaction to certain environmental factors, such as chemicals, pollutants, or certain types of weather.
Symptoms
Symptoms of intolerance can vary depending on the type of intolerance and the individual's sensitivity. Common symptoms can include:
- Digestive problems such as bloating, gas, or diarrhea
- Skin problems such as rashes or itching
- Respiratory problems such as wheezing or shortness of breath
- Neurological problems such as headaches or migraines
Diagnosis
Diagnosis of intolerance often involves a process of elimination, where potential triggers are removed from the person's diet or environment to see if symptoms improve. Other diagnostic tools can include blood tests, skin tests, and elimination diets.
Treatment
Treatment for intolerance often involves avoiding the trigger substance or factor. In some cases, medications may be used to manage symptoms.
