What Is a Possible Cause for My Loss of Smell and Taste?

Anosmia and ageusia may be signs of an underlying disease, which can affect your quality of life. Problems with taste and smell might indicate various health issues, such as:

• Diabetes
• Kidney disease
• Obesity
• Poor nutrition
• High blood pressure
• Nervous system disease
  • Multiple sclerosis
  • Parkinson’s disease
  • Alzheimer’s disease

Sense of smell and taste greatly improve one’s quality of life. Here are some factors that explain the importance of smell and taste:

• The fragrance of food stimulates appetite, and a loss of smell can result in a loss of appetite and interest in food.
• Saliva production can be reduced if you lose your sense of smell, making dry foods, such as biscuits and crackers, more difficult to eat as a result of this.
• Changes in taste may cause you to avoid certain items, such as meat, resulting in a nutrition deficiency and potentially misleading you into adding more spice and salt to food that may later cause medical issues, such as gastric irritation and high blood pressure.
• Consumption of rotten/spoiled food is harmful to the body, and your sense of smell and taste helps you identify and avoid spoiled food and contaminated water.
• In the absence of smell and taste, your satiety reduces, which makes you eat more leading to health issues and weight gain.
• Sense of smell and taste help form new memories and recall old ones, causing a powerful emotional response.
• Smell and taste also act as warning signs and alert us about harmful events such as a gas leak, toxic chemical fumes or fire.
• When you lose your sense of smell, you may not realize when you need to take a bath, apply deodorant or wash your clothes, which may result in a lack of hygiene.
• With damage to the areas that deal with smell and taste, other nearby sections of the brain may also be affected, leading to several problems, including:
  • Emotional problems such as depression and irritability
  • Behavioral problems such as aggressiveness and impulsiveness
  • Inability to understand and respond well to other’s feelings and needs

If you observe any changes in your sense of smell and taste, you must consult an otolaryngologist who specializes in the diagnosis and treatment of conditions related to the ear, nose and throat, along with the mouth and parts of the neck and face. They examine and perform special tests to identify the cause of the condition and provide treatment accordingly.
