Summary
Older age and longer duration of type 2 diabetes mellitus (DM) are linked to reduced olfactory function. Comorbidities did not significantly impact smell in patients with type 2 DM.
Area of Science:
- Endocrinology
- Otolaryngology
- Neuroscience
Background:
- Type 2 Diabetes Mellitus (DM) is frequently associated with olfactory dysfunction.
- The impact of disease duration and comorbidities on olfactory function in DM patients requires further clarification.
Purpose of the Study:
- To investigate the correlation between type 2 DM duration, comorbidities, and olfactory function.
- To identify factors influencing olfactory dysfunction in patients with type 2 DM.
Main Methods:
- An analytical observational study involving 66 type 2 DM patients.
- Data collected via medical records, questionnaires, ENT examinations, and the Sniffin' Sticks Test.
- Statistical analysis performed with significance set at P<0.05.
Main Results:
- A significant negative correlation was found between age and olfactory function score (P=0.012).
- A significant negative correlation was observed between type 2 DM duration and olfactory function score (P=0.005).
- No significant relationship was found between sex or comorbidities and olfactory function.
Conclusions:
- Increasing age and longer duration of type 2 DM are associated with diminished olfactory function.
- Comorbidities do not appear to significantly alter olfactory function in type 2 DM patients.
- These findings contribute to understanding olfactory dysfunction in type 2 DM.

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...

Chronic stress has been linked to both the onset and progression of serious health conditions, including Type 2 diabetes and cancer. Type 2 diabetes, a widespread chronic illness, is closely associated with obesity and insulin resistance, both of which often worsen under stress. Studies indicate that men experiencing high levels of chronic stress face a 45% higher risk of developing diabetes compared to those with minimal stress. Stress triggers physiological responses that elevate blood...

Diabetes mellitus is a chronic metabolic disorder characterized by hyperglycemia. The four categories of diabetes are type 1 diabetes, type 2 diabetes, other specific types of diabetes, and gestational diabetes.
Type 1 diabetes is characterized by autoimmune-mediated destruction of pancreatic β cells, with environmental factors potentially triggering this process in genetically susceptible individuals. Despite many not having a family history, certain genes increase susceptibility,...

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...
