Summary
Individuals with type 1 diabetes show impaired taste recognition, particularly for bitter and sour flavors, compared to healthy controls. This taste dysfunction may be linked to the age at which type 1 diabetes onset occurred.
Area of Science:
- Endocrinology
- Neuroscience
- Sensory Science
Background:
- Altered taste function in type 1 diabetes has been inconsistently reported.
- Understanding taste perception changes is crucial for managing diabetes-related complications.
Purpose of the Study:
- To evaluate taste recognition and intensity in young individuals with type 1 diabetes compared to healthy controls.
- To investigate associations between taste perception and personal/clinical characteristics in type 1 diabetes.
Main Methods:
- Taste recognition and intensity for PROP, quinine, citric acid, sucrose, and sodium chloride were assessed using a filter paper method.
- 276 participants with type 1 diabetes and 147 healthy controls were included.
- Regression analysis adjusted for sex, age, and BMI.
Main Results:
- Fewer participants with type 1 diabetes recognized all tastes (47%) compared to controls (63.5%).
- Impaired recognition of bitter (PROP) and sour (citric acid) tastes was observed in the type 1 diabetes group.
- No significant effect of glycemic control was found, but lower age at onset was associated with impaired taste recognition.
Conclusions:
- Individuals with type 1 diabetes exhibit impaired taste perception.
- Age at onset appears to be a significant factor associated with taste dysfunction in type 1 diabetes.

Diabetes mellitus is a chronic metabolic disorder characterized by high blood glucose levels due to inadequate insulin production, insulin resistance, or both. The condition affects millions worldwide and can significantly impact their health and quality of life.
Type 1 diabetes is an autoimmune disease in which the immune system mistakenly attacks and destroys the insulin-producing beta cells in the pancreas. As a result, the body is unable to produce sufficient insulin, and individuals with...

3.0K
Gustation, or the sense of taste, is intrinsically linked to the anatomical structures located on the tongue. This organ's surface, along with the entirety of the oral cavity, is adorned with stratified squamous epithelium. Evident on the tongue are elevated structures known as papillae (singular = papilla), which house the mechanisms for the transduction of gustatory stimuli. Four distinct types of papillae exist, each identified by their unique morphological attributes: the circumvallate,...

3.1K
Type 2 diabetes, characterized by insulin resistance, arises when the insulin receptors on cells lose responsiveness to insulin, diminishing the cell's capacity to take up glucose, resulting in elevated blood glucose levels. To receive a diagnosis of Type 2 diabetes, a series of blood glucose tests are necessary to assess whether the blood glucose falls within normal parameters. If the result is out of the normal range, a patient may be diagnosed as prediabetic or diabetic, depending on the...

For most patients, experiencing several weeks of polyuria, polydipsia, fatigue, and significant weight loss may indicate the presence of diabetes. Furthermore, adults displaying the phenotypic appearance of type 2 diabetes (particularly those who are obese and not initially insulin-requiring), may have islet cell autoantibodies, suggesting autoimmune-mediated β cell destruction and a diagnosis of latent autoimmune diabetes of adults (LADA). The categorization of glucose homeostasis is...

Insulin-replacement therapy usually includes both long-acting insulin (basal) and short-acting insulin (to cater to postprandial needs). In a diverse group of type 1 diabetes patients, the average daily insulin dose is typically 0.5-0.7 units/kg body weight. However, obese patients and pubertal adolescents may need more due to insulin resistance.
The basal dose constitutes about 40%-50% of the total daily dose, with the rest as premeal insulin. The mealtime insulin dose should mirror...

Carbohydrates are polymers composed of molecules containing atoms of carbon, hydrogen and oxygen. One gram of carbohydrate can provide four kilo-calories of energy, which makes it the most efficient instant energy source.
Starch accounts for approximately 60% of the carbohydrates consumed by humans. Since amylase enzymes cannot function in the stomach's acidic environment, starch can only be digested in the mouth and small intestine. Simple sugars are found naturally in milk and fruits in...
