As we age, does our sensitivity to taste and smell decrease?

Yes, generally speaking, as we age, especially after the age of 60, our sensitivity to taste and smell decreases. This is part of the natural aging process. Of course, other factors can also lead to the loss of taste and smell, including:

• Nasal and sinus problems such as allergies, sinusitis, and nasal polyps.
• Certain medications, such as beta-blockers and ACE inhibitors used to treat high blood pressure.
• Dental issues or poor oral hygiene.
• Smoking.
• Head or facial injuries.
• Alzheimer's disease.
• Parkinson's disease.

The loss of taste and smell can significantly affect quality of life, often leading to decreased appetite and malnutrition. Sometimes, the loss of taste and smell can also cause depression. Additionally, as taste and smell become less sensitive, you might add more salt or sugar to your food to enhance flavor, which is not good for people with high blood pressure or diabetes.

If you notice a gradual loss of taste and smell sensitivity, it is best to see a doctor. If it is caused by aging, there might not be much that can be done. However, if it is caused by other factors, it might be treatable. For example, for taste and smell issues caused by medication, a doctor can try adjusting the dosage or changing the medication. For issues caused by oral, nasal, or sinus diseases, a doctor can provide appropriate treatment. If smoking is the cause, quitting smoking can help restore taste and smell.
