Fructose intolerance is a condition in which a person cannot properly digest fructose. The spelling of "fructose" is pronounced /ˈfrʌktəʊs/ in IPA, with the stress on the first syllable. The word "intolerance" is pronounced /ɪnˈtɒlərəns/ in IPA, with the stress on the second syllable. The word is spelled in accordance with the English language's standard phonetic rules, where each letter represents a sound. Understanding the IPA phonetic transcription can help with pronunciation and improve communication in medical settings.
Fructose intolerance is a metabolic disorder characterized by the inability to digest fructose, a simple sugar found in plenty of fruits, vegetables, and other natural and processed foods. This condition is caused by a lack of or deficiency in an enzyme called fructose-1-phosphate aldolase, which is necessary to break down fructose into simpler forms for absorption by the body.
When an individual with fructose intolerance consumes foods containing fructose, the undigested sugar accumulates in the intestines, leading to various symptoms. These symptoms may include abdominal pain, bloating, diarrhea, nausea, and vomiting. In some cases, fructose intolerance may also cause headaches, excessive thirst, fatigue, and mood swings. The severity of these symptoms can vary for each person depending on the amount of fructose consumed and the individual's tolerance level.
Diagnosis of fructose intolerance typically involves a combination of medical history evaluation, physical examination, and laboratory tests. The most common diagnostic method is a breath test, where patients are required to consume a controlled amount of fructose and then exhale into a device to measure the levels of hydrogen produced, which can indicate fructose malabsorption.
Management of fructose intolerance mainly revolves around avoiding foods that contain high fructose levels, such as certain fruits, sweeteners, and processed food products. A low-fructose or fructose-free diet may be recommended to alleviate symptoms and prevent further complications. Consulting a healthcare professional, such as a gastroenterologist or a registered dietitian, can provide personalized guidance and support for individuals dealing with fructose intolerance.
The word "fructose" comes from the Latin term "fructus", which means "fruit". It refers to a natural sugar found in fruits, honey, and some vegetables. "Intolerance" is derived from the Latin term "intolerantia", meaning "inability to endure or bear". When combined, "Fructose Intolerance" refers to the inability to digest or metabolize fructose properly.
