What diseases should one be alert to when smelling vegetable odor

Smelling abnormal vegetable flavors may be a sign of olfactory dysfunction, and one should be alert to diseases such as rhinitis, sinusitis, olfactory nerve damage, premonitory epilepsy, or Alzheimer's disease. Abnormal sense of smell is usually related to nasal diseases, neurological disorders, or metabolic diseases. If it persists for a long time, it is recommended to seek medical examination and screening as soon as possible.

1. Nasal diseases

Chronic rhinitis or sinusitis may cause damage to olfactory cells, leading to abnormal olfaction such as vegetable flavor. Patients often have symptoms such as nasal congestion and purulent discharge, and repeated inflammation can exacerbate olfactory abnormalities. During the acute attack period, nasal glucocorticoid spray can be used according to the doctor's advice, such as budesonide nasal spray. When combined with bacterial infection, antibiotic treatment is required.

2. Neurological injury

Head trauma or viral infection may damage the olfactory nerve, leading to olfactory dysfunction or hallucinations. After cranial surgery, some patients may experience persistent vegetable flavored hallucinations, which require neurological assessment of the degree of injury. Nutritional neuropharmaceuticals such as mecobalamin tablets may help with repair, but recovery from severe injuries is more difficult.

3. Seizure premonitory

Before a temporal lobe seizure, there may be a special odor such as vegetable flavor, which usually lasts for a few seconds and is accompanied by consciousness disorders. This symptom is repetitive and stereotyped, and abnormal discharge can be detected by EEG examination. Antiepileptic drugs such as sodium valproate tablets can effectively reduce seizure frequency and require long-term medication control.

4. Degenerative diseases

Alzheimer's disease may present with olfactory recognition disorders in the early stages, and some patients may smell non-existent odors. Olfactory testing combined with cognitive assessment is helpful for early diagnosis, while cholinesterase inhibitors such as donepezil tablets can delay disease progression. Abnormal sense of smell often appears earlier than memory loss.

5. Metabolic disorder

In case of diabetes ketoacidosis, the accumulation of ketones in the body may produce special smell perception. Patients with liver and kidney failure may also experience olfactory abnormalities such as vegetable odor due to the accumulation of metabolic waste. This situation requires urgent treatment of the primary disease and correction of internal environmental disorders through measures such as fluid replacement and dialysis.

Daily attention should be paid to keeping the nasal cavity clean and avoiding contact with irritating gases. A balanced diet supplemented with vitamin B and zinc elements can help maintain olfactory function, and regular sleep can reduce neurological abnormalities. If the abnormal sense of smell persists for more than two weeks, or is accompanied by symptoms such as headache and dizziness, immediate nasal endoscopy, head MRI, and other examinations should be performed. Olfactory problems may be early signals of serious diseases, and early diagnosis and treatment can significantly improve prognosis.
