If you don't have a desire or willingness to have sex, it is probably due to low sex drive or libido. It may be connected to fluctuations in hormones that play a key role in regulating sexual desire. Emotional well-being, stress levels, and mental health conditions like depression or anxiety can impact libido as well. Vitamin B12 deficiency may also be the reason behind low sex drive. Lacking this vitamin in your body can lead to fatigue and weakness, and mood changes that can all affect your libido. Since vitamin B12 can improve your sex drive, make sure to include it in your diet.

What are the causes of low sex drive?

Several factors can lead to low sex drive in women, including:

1. Hormonal changes

Fluctuations in hormones, particularly estrogen and testosterone, can significantly impact libido. "Menstruation, pregnancy, breastfeeding, and menopause often lead to hormonal shifts that may reduce sexual desire," says obstetrician and gynaecologist Dr Kanupriya Jain.

2. Stress and anxiety

Emotional stress from work, relationships, or other pressures in life can diminish interest in any kind of sexual activity. Anxiety can also affect overall well-being, making it harder to feel relaxed and in the mood.

3. Fatigue

Physical exhaustion or poor quality of sleep can reduce your energy levels and motivation for any sexual activity. "This is especially common in women balancing multiple responsibilities," says the expert.

4. Medications

Some medications, particularly antidepressants, can have side effects that lower sex drive. One of the common side effects of antidepressants is sexual dysfunction, as per research published in Dovepress in 2010.

5. Relationship issues

A lack of emotional connection, unresolved conflicts, or poor communication with a partner can lead to decreased sexual desire. "Trust and intimacy are essential for maintaining sex drive," says the expert.

6. Body image and self-esteem

Negative feelings about your own body can impact confidence and reduce the desire for sexual intimacy. "Feeling comfortable and confident in your own body can improve sexual desire," says Dr Jain.
