Not only breathing is done through the nose, but also the scent of any object or things. Scent is closely related to the increase in taste or distaste for food. However, the sense of smell in the nose can give an idea in advance to identify various diseases of the body!
Scientists have discovered such an amazing thing. According to a recent study, problems with the sense of smell are not only uncomfortable, but can also be an early symptom of many diseases.
According to the research paper published in Frontiers in Molecular Neuroscience journal, loss of smell is associated with at least 139 different diseases. These diseases include Alzheimer's, heart disease and diabetes.
Therefore, the lack of smell in the nose can be a sign of various diseases in the human body.
In many cases, people lose their sense of smell before the general symptoms of various diseases appear in the body.
Research by a team at the University of California has shown that people who are diagnosed with Parkinson's disease (nervous system disease) lose their sense of smell long before the symptoms of the disease appear.
Similarly, people with Alzheimer's disease often cite loss of smell as their primary symptom. They lose their sense of smell even before they develop any memory problems. They also noted a clear correlation between inflammation in different parts of the body and loss of smell in the nose.
The nervous system related to smell is the olfactory. This sensory system of the human body is directly connected to the memory center of the brain.
Researchers say 139 diseases are associated with loss of smell. They divided these diseases into three main categories—neurological (related to the brain and nervous system), somatic (related to different parts of the body) and congenital or hereditary.
These range from mental health problems, such as depression and anxiety, to physical diseases, such as diabetes and heart disease.
According to research reports, people can get relief from many symptoms of these diseases by stimulating the olfactory nerve system. For this the olfactory can be trained by sniffing various strong and pungent odors.
New research has shown that dementia patients who smelled 40 different smells twice a day for two weeks improved their memory, attention and language skills.
Professor Michael Lyon, who led this innovative approach, said: 'We previously reported that improving the sense of smell could improve memory in the elderly by 226 per cent. And now that we know that scents can help reduce inflammation, these scents can improve brain health.
List of diseases associated with loss of sense of smell:
Neurological Disorders: Alzheimer's, Parkinson's, Multiple Sclerosis, Depression, Anxiety, Autism, Epilepsy, Chronic Fatigue Syndrome, Delirium, Chronic Covid, Migraine, Sleep Disorders, Post-Traumatic Stress Disorder (PTSD), Schizophrenia, Traumatic Brain Injury , stroke, cluster migraine, fibromyalgia, various types of dementia and other conditions related to brain and nerve activity.
Body Wide Conditions (Physical Problems): Covid 19, Heart Disease, Diabetes, Obesity, Cancer (Head and Neck), HIV AIDS, Allergy, Asthma, Arthritis, Celiac Disease, Crohn's Disease, Cirrhosis, Kidney Disease, Malnutrition, High Blood Pressure, Thyroid Problems, Vitamin B12 deficiency, Vitamin D deficiency are numerous other conditions affecting different body systems.
Genetic conditions (genetic problems): Down syndrome, Fragile X syndrome, cystic fibrosis, Wilson's disease, various rare genetic disorders that affect metabolism.
