Hormones

LH

Luteinizing Hormone (LH) plays a crucial role in triggering ovulation and maintaining reproductive hormone balance.

What it is

Luteinizing Hormone (LH) plays a crucial role in triggering ovulation and maintaining reproductive hormone balance. High LH levels may indicate polycystic ovary syndrome (PCOS) or menopause, while low LH levels can be linked to hypothalamic dysfunction or pituitary disorders. Monitoring LH levels helps assess ovarian function, menstrual cycle regularity, and fertility potential, ensuring hormonal balance for reproductive and metabolic health.

What affects your levels

High LH is often caused by PCOS, menopause, or excessive exercise. Insulin resistance and chronic stress can contribute to imbalances. Low LH may result from hypothalamic dysfunction, chronic illness, eating disorders, or excessive weight loss. Pituitary disorders and hormonal contraceptives can also suppress LH production. Identifying the underlying cause of LH imbalances helps maintain reproductive function and prevent menstrual irregularities.

Signs and symptoms

For high LH, refined sugars, trans fats, and highly processed foods can worsen insulin resistance and hormonal imbalances. Excess alcohol and artificial additives may further disrupt LH regulation. For low LH, extreme calorie restriction and excessive caffeine intake should be avoided. Reducing dietary stressors while focusing on whole, hormone-supportive foods promotes stable LH levels, supporting reproductive and metabolic health.

Foods that help

For low LH, nutrient-dense foods like fatty fish, whole grains, and legumes support hormone production. Zinc from shellfish and vitamin D from eggs and dairy promote ovulation. For high LH, anti-inflammatory foods like leafy greens, berries, and turmeric support metabolic balance. A well-rounded diet with balanced macronutrients helps regulate LH levels, improving ovarian function and fertility.

Foods to limit

For high LH, refined sugars, trans fats, and highly processed foods can worsen insulin resistance and hormonal imbalances. Excess alcohol and artificial additives may further disrupt LH regulation. For low LH, extreme calorie restriction and excessive caffeine intake should be avoided. Reducing dietary stressors while focusing on whole, hormone-supportive foods promotes stable LH levels, supporting reproductive and metabolic health.
