Autonomic neuropathy affects blood pressure regulation, heart rate, sweating, digestion, and bladder function. Symptoms are often overlooked.

Autonomic neuropathy refers to damage to the nerves that regulate involuntary bodily functions. These nerves control heart rate, blood pressure, sweating, digestion, bladder function and sexual function. When they are damaged, the body loses its ability to regulate these processes automatically, and symptoms are often subtle or attributed to other causes.
Orthostatic hypotension is a hallmark symptom. Standing from a sitting or lying position causes a drop in blood pressure that produces dizziness, lightheadedness, visual dimming or fainting. Patients may notice symptoms are worse in the morning, in hot weather, or after meals. In some cases, the drop is severe enough to cause falls, particularly in older adults.
Dr. Jitendra Prasad Yadav — consultant neurologist & headache specialist at Kathmandu Neurology Clinic & Cognitive Center provides evidence-based evaluation for peripheral neuropathy.
Gastroparesis causes delayed stomach emptying, leading to bloating, nausea, early satiety and sometimes vomiting of undigested food hours after eating. Blood sugar control becomes difficult because food absorption timing is unpredictable. Bladder dysfunction presents as urinary retention, incomplete emptying, frequency or urgency, and recurrent urinary tract infections may follow. Sweating abnormalities range from reduced sweating with heat intolerance to excessive compensatory sweating in other areas.
Erectile dysfunction in men and reduced lubrication in women are common autonomic manifestations that patients may be reluctant to discuss but which significantly affect quality of life. Evaluation at Kathmandu Neurology Clinic & Cognitive Center includes cardiovascular autonomic testing, sweat testing where available, and targeted laboratory investigations to identify reversible causes such as diabetes, B12 deficiency, thyroid disease and medication effects.
Dr. Jitendra Prasad Yadav (NMC 8029) evaluates autonomic symptoms systematically at Durbar Marg, Opposite of Yak & Yeti Hotel. Bring a complete medication list, as many medications contribute to autonomic dysfunction.

Supplements only help when a deficiency is present; underlying cause-directed care is needed.
If the underlying cause is corrected early (e.g., improving glucose control, treating vitamin deficiency), improvement may occur. Long-standing neuropathy is often not fully reversible.
Migraine is a neurological condition; headache is one feature. Associated symptoms and functional impact are important for diagnosis.
Aura refers to visual, sensory, or speech symptoms that precede the headache in some people. Both types are migraine; the presence of aura may influence management discussion.
