Hair loss and weight gain can go hand in hand. The effects of obesity often include fatigue, breathing difficulties, and knee pain. However, hair loss is not directly caused by excess weight. Instead, it may be related to deficiencies or underlying health conditions associated with obesity.
This article explains the possible connection between weight gain and hair loss if you are experiencing both. Take a look:
Hair Loss and Weight Gain: What is the Connection?
Excessive weight gain and a high body mass index (BMI) are associated with multiple health problems and metabolic syndromes that can trigger hair loss. Numerous studies have found a link between weight gain and hair loss:
A study on men in Taiwan reported that a higher BMI could increase the severity of androgenetic alopecia (hair loss).
Metabolic syndromes, such as waist circumference and high blood pressure, also trigger hair loss. One study demonstrated that baldness extends with weight gain.
Another study on middle-aged women concluded that insulin resistance could increase the risk of androgenic alopecia, especially in women with a family history. Obesity is one of the causes of insulin resistance.
Several conditions can trigger unexplained weight gain. This complex process can lead to a cascade of problems, including hair loss. In the following section, we will look at the possible causes of significant weight gain and hair loss.
Causes of Hair Loss and Weight Gain in Women
1. Thyroid Disorders
The thyroid gland is responsible for regulating multiple metabolic functions in the body. An imbalance of thyroid hormones is linked to alopecia areata. Hair follicles have receptors that bind to thyroid-stimulating hormone (TSH).
Studies have found that a lack of thyroid hormones and hypothyroidism, particularly hormones T3 and T4, could cause hair loss, lack of hair pigmentation, and other issues. Thyroid disorders are associated with dry skin, fatigue, and irregular periods.
2. Hormonal Imbalance During Pregnancy
The hair cycle in women changes during pregnancy, and diffuse hair loss is common in postpartum women. Although the exact mechanism is unclear, changes in reproductive hormone levels may be a possible reason. It is normal to experience hair loss and weight gain in these situations. However, the hair cycle normalizes once hormone levels stabilize.
3. Polycystic Ovary Syndrome
Women with this syndrome face abnormalities in androgen and estrogen metabolism.
Excess estrogen is often linked to both weight gain and hair loss. On the other hand, excessive androgen levels or hyperandrogenism cause hair loss in women.
4. Menopause
During menopause, estrogen and progesterone levels decrease in women. Low progesterone levels often lead to increased androgen levels. This hormonal change during menopause is responsible for hair loss, mood changes, and weight gain.
5. Stress
Stressful situations, such as surgery, psychological and emotional stress, accidental dieting, illness, and injuries, can affect the normal hair cycle and cause telogen effluvium (hair loss). Increased cortisol levels lead to the redistribution of adipose tissue in the abdominal region, increasing appetite. This often leads to abdominal obesity. It also affects metabolism and causes various metabolic syndromes.
However, the relationship between excess androgens (such as testosterone) and hair loss in women is unclear. It is speculated that androgen derivatives (especially DHT) block hair follicles, causing hair loss.
6. Adrenal Fatigue
Long-term stress activates the adrenal glands and causes adrenal fatigue. These glands regulate adrenaline and cortisol. When overworked, they produce more cortisol and cannot keep up with other demands of the body, leading to fatigue, insomnia, weight gain, low immunity, and hair loss. Animal studies have linked hair loss to increased adrenal activity.
The best way to combat this is to take care of your diet and sleep patterns. Improve your lifestyle by managing stress and engaging in physical activity to minimize adrenal fatigue.
7. Prescription Medications
Prescription medications, such as antidepressants, anticonvulsants, and corticosteroids, can cause weight gain and hair loss. Medication-induced hair loss is temporary, and normal hair growth resumes once treatment is stopped. Consult a specialist if hair loss persists.
8. Poor Nutrition
Consuming unhealthy and processed foods and lacking a proper diet can harm your health, leading to weight gain and hair loss. A lack of essential nutrients and trace elements such as iron, zinc, fatty acids, vitamins A and E, amino acids, biotin, and proteins can cause hair loss.
Key Recommendations
Studies indicate that excessive weight gain and a high body mass index (BMI) can lead to androgenic alopecia.
A lack of thyroid hormones, polycystic ovary syndrome, and stress are some factors contributing to weight gain and hair loss in women.
A diet rich in processed foods and low in essential nutrients, along with prescribed medications such as antidepressants and corticosteroids, has been linked to hair loss and weight gain.
Maintaining physical activity, good sleep, and a balanced diet can help you keep your weight under control and promote hair growth.
