ízérzészavar

Izérzészavar, also known as dysgeusia, is a medical term referring to an altered or abnormal sense of taste. It can manifest in various ways, including a metallic, bitter, sour, or salty taste that is not caused by anything in the mouth. Some individuals may experience a complete loss of taste, known as ageusia, or a reduced sense of taste, called hypogeusia. These disturbances can affect one or more of the five basic taste sensations: sweet, sour, salty, bitter, and umami.

The causes of izérzészavar are diverse. It can be a side effect of certain medications, particularly those used in chemotherapy, antibiotics, and blood pressure treatments. Infections, such as upper respiratory infections or oral thrush, can also lead to taste disturbances. Neurological conditions like Bell's palsy, head injuries, or brain tumors that affect the nerves responsible for taste can be implicated. Furthermore, exposure to certain chemicals or heavy metals, nutritional deficiencies (e.g., zinc or vitamin B12 deficiency), and hormonal changes associated with pregnancy or menopause can contribute to dysgeusia. Dry mouth (xerostomia), often a side effect of medications or medical conditions like Sjögren's syndrome, can also impair taste perception by reducing saliva flow. Dental problems, such as gum disease or poorly fitting dentures, can also play a role.

Diagnosing izérzészavar typically involves a thorough medical history, a physical examination, and sometimes specific taste tests to assess the sensitivity to different flavors. Treatment strategies depend on the underlying cause. If a medication is responsible, adjusting the dosage or switching to an alternative may resolve the issue. Addressing infections, treating nutritional deficiencies, and managing underlying medical conditions are also crucial. In some cases, saliva substitutes or dietary modifications may help alleviate symptoms.
