Sometimes it seems that there is no life in the body? Do you feel tired throughout the day, weak and without any heavy work, feel “lack of energy”? If yes, then it is not just the result of sleep or more work – rather it can be a sign of many deep reasons to health.

The most common cause of fatigue in women

1. Lack of iron element (iron) – anemia
57% of India’s 15–49 years of age suffer from anemia. Lack of iron decreases hemoglobin in the body, which reduces oxygen delivery and gives symptoms like persistent fatigue, weakness and breathlessness. Women need more iron during menstruation and pregnancy. Eating iron with green greens, vegetables, pulses, and vitamin-C is beneficial.

2. Vitamin B12 deficiency
B12 is the main nutrient of red blood cells and nerve function. Especially in vegetarian women and the elderly, it is more lacking, which can cause tiredness, lethargy, weakness, even memory or nerve problems. Eggs, dairy, fortified grains and B12 supplements can help.

3. Vitamin D deficiency
Vitamin D is reduced by not getting enough sunlight, changing lifestyle, dark skin, and time indoors. Vitamin D deficiency causes muscle weakness, bone pen, and fatigue. Consumption of fortified milk, fish, or supplement is beneficial in the sun for 15-20 minutes daily.

4. Thyroid problem
Metabolism slows down from underactive or overactive thyroid, which can cause problems at all times, weight gain/phenomenon, mood swings, hair loss etc. It is necessary to treat it according to the advice of the doctor.

5. Chronic stress and poor sleep quality
Due to work pressure, domestic responsibility, or emotional stress, sleep does not get perfect, which can lead to persistent tiredness and burnout. Good quality sleep, meditation, and routine checkup from time to time are necessary.

6. Lifestyle and flaws in catering
Unhealthy diet, dehydration, lack of physical activity, processed foods also reduce energy. Adequate nutrition, regular exercise and hydration are necessary.

Even more possible cause

Hormonal changes (menstruation, pregnancy, menopause)

Diabetes, heart disease, anxiety-depression, side effects of medicines

Sleeping of sleeping time, frequent sleep obstruction

Irregular lifestyle and constant work

When to see the doctor?

If fatigue remains for weeks, life is affected by lethargy, frequent headaches, heartbeat, or the skin looks yellow-see a doctor without delay. A simple blood test can reveal common causes like iron, B12, vitamin D, thyroid.

Practical Tips:

Include green leafy vegetables, pulses, milk and fruits in your diet.

Keep a fixed time for sleeping, sleep at least 7-8 hours.
