Loss of sense of smell is not a good omen

In a study conducted with 2,300 people over the age of 70, it was seen that those with a weak sense of smell were 46 percent more likely to die within 10 years.

Epidemiologist Honglei Chen of Michigan State University said: “As people age, a decreased sense of smell is more common and is associated with a higher risk of death. In our study, we examined why this could be a precursor to a higher mortality rate.” says.

Using data from the National Institute of Aging Health, Chen and his research team analyzed 13 years of data from nearly 2,300 people aged 71 to 82. Participants included women, men, blacks and whites. Participants were tested for 12 common odors. The researchers classified the participants’ sense of smell as good, moderate, and poor.

46 percent higher risk of death

Compared with other adults with a good sense of smell, people with poor sense of smell were 46 percent more likely to die within 10 years and 30 percent more likely to die within 13 years.

Gender, race, and other demographics and lifestyles appeared to have minimal impact on outcomes. However, it was determined that among the healthy participants at the beginning of the study, those with a weak sense of smell had a higher risk of death.

The association of 70 percent of deaths with odor could not be explained.

Weakened sense of smell is known as an early sign of Parkinson’s disease and dementia and is associated with weight loss. However, these conditions can only explain 28 percent of the increased risk. The rest are still waiting for an explanation. “We haven’t been able to find any reason for more than 70 percent of the increased risk,” Chen said. We need to find out what happened to these individuals.” He stated that they will focus on this in future studies.

Chen also says that a poor sense of smell can be an early and sensitive sign that health is deteriorating while a doctor hasn’t detected it. “This shows us that the loss of the ability to smell in older adults can have consequences far beyond what we know.” “It might be a good idea to have a smell ability test at routine doctor visits,” said Chen. he said.

So if you’re having trouble smelling, it’s a good idea to talk to a doctor. “It is always a good idea to raise any concerns about your health to a doctor,” Chen said. says.
