Neha’s Tingling Fingers

Neha Verma, nineteen, was a first-year student living in a hostel in Delhi. She was a strict vegetarian and survived on instant noodles, tea and biscuits. She rarely went out in the sun because she studied or slept in the afternoon. By the end of the semester she was tired all the time, her mood was low, she cried easily, and her fingers sometimes tingled. She had stomach upsets and her muscles ached.

Her friend Zara thought it was exam stress. Her mother thought she was homesick. But when Neha mentioned the tingling during a call home, her mother, who knew a little about nutrition, insisted she see a doctor.

The doctor asked about her food and routine, examined her, and ordered blood tests. They showed low levels of vitamin D and vitamin B12. Both are needed by the brain and nerves: B vitamins help make brain chemicals and protect nerves, and vitamin D affects mood and bone strength. The doctor advised treatment, and also changes to her diet, getting sunlight sensibly, and eating more varied foods, including pulses, dairy, greens and fruit.

The doctor also talked about the gut, the 'second brain', whose health and the food we eat connect with how we feel. Within a couple of months, Neha's energy improved and the tingling went. She said, 'I was ready to quit college because I thought I was weak. I was undernourished.'

How to recognise it

Constant tiredness, low mood, irritability or tearfulness with a poor and limited diet.
Tingling or numbness in hands or feet, muscle aches or weakness.
Poor concentration, memory difficulties or feeling mentally foggy.
Very little sun exposure or very restricted eating, such as only snacks.
Stomach problems such as constipation, bloating or poor appetite.

What this story explains

The chapter's sections on vitamins, minerals and the gut-brain axis show how poor nutrition, low vitamin D and low B12 can affect mood, nerves and thinking. It also lists physical conditions that can look like mental illness.

Probable root causes

Limited, repetitive diet with few vegetables, pulses, dairy or fruit.
Low sun exposure and indoor lifestyle.
Low vitamin B12, which is common when intake of animal-based foods is low or absorption is poor.
Stress and irregular sleep, and gut problems that reduce absorption.

What to do

Review what you actually eat in a week, honestly.
Add a variety of home-style foods: pulses, dairy or eggs if you eat them, greens, fruit and nuts.
Get some daily sunlight on skin, as advised for your area and skin type.
Ask a doctor to test for vitamin levels before taking supplements.
Follow the doctor's advice and return for repeat tests; add sleep and activity.

Whom to consult

Family doctor or college health centre for blood tests when tiredness, low mood and tingling occur together.
Dietitian or nutritionist for planning affordable, varied meals.
Neurologist if numbness, weakness or balance problems are marked or persist.
Counsellor or psychiatrist if low mood continues after the body is treated.

Do and don’t

Do	Don’t
Do eat regular, varied meals.	Don't live on snacks and noodles.
Do get checked before assuming it is only stress.	Don't self-prescribe vitamins in large amounts.
Do take supplements only if the doctor prescribes them.	Don't ignore tingling or numbness.
Do spend time outdoors in daylight.	Don't treat food as a cure for serious depression.

How to behave and communicate

Be caring: 'You sound very tired. Can we look at what you are eating and get tests done?'
Avoid food shaming; offer to cook or share meals.
Listen to both physical and emotional complaints.
Reassure: 'This can be treated, and it is not a weakness.'
Check in again after a few weeks.
