Hypoesthesia
Hypoesthesia (pronounced: hi-po-es-thee-zha) is a medical term that refers to a reduced sense of touch or sensation, or a partial loss of sensitivity to sensory stimuli. In everyday language, hypoesthesia is often described as having a "numb" feeling.
Etymology
The term hypoesthesia comes from the Greek words 'hypo' meaning 'under' or 'beneath', and 'aisthesis' meaning 'sensation'.
Symptoms
Hypoesthesia is typically characterized by a diminished sense of touch or sensation, or a partial loss of sensitivity to sensory stimuli. This can occur in one particular area of the body, such as the hands or feet, or it can be more generalized.
Causes
Hypoesthesia can be caused by a variety of conditions, including peripheral neuropathy, multiple sclerosis, stroke, and diabetes. It can also be a side effect of certain medications.
Diagnosis
Diagnosis of hypoesthesia is typically made through a physical examination and a review of the patient's medical history. Additional tests, such as nerve conduction studies or an magnetic resonance imaging (MRI) scan, may also be used to determine the underlying cause of the hypoesthesia.
Treatment
Treatment for hypoesthesia typically involves addressing the underlying cause of the condition. This may involve medication, physical therapy, or in some cases, surgery.
