Oligomenorrhea, which refers to infrequent or irregular menstrual periods, with intervals of 35 days or more between cycles, and sometimes up to three or four months.

Common Causes of Oligomenorrhea:

1. Polycystic Ovarian Syndrome (PCOS): One of the most common causes of irregular periods due to hormonal imbalances, often accompanied by weight gain, acne, and excessive hair growth.
2. Thyroid Disorders: Both hypothyroidism (underactive thyroid) and hyperthyroidism (overactive thyroid) can affect menstrual regularity.
3. Hormonal Imbalance: Imbalances in estrogen and progesterone can disrupt the menstrual cycle.
4. Perimenopause: In women approaching menopause (late 40s to early 50s), periods become irregular.
5. Stress: Physical or emotional stress can interfere with the menstrual cycle.
6. Weight Issues: Sudden weight gain, obesity, or extreme weight loss can disrupt normal ovulation.
7. Chronic Illnesses: Conditions like diabetes or celiac disease can affect the regularity of menstrual cycles.
8. Excessive Exercise: Intense physical activity can suppress reproductive hormones.
9. Use of Hormonal Contraceptives: Some birth control pills or injections can cause delayed or missed periods.
10. Pituitary Disorders: Issues like prolactinoma, which affect the pituitary gland, can disrupt menstrual cycles.

Homeopathic Remedies for Oligomenorrhea:

1. Pulsatilla: Often used for women with irregular, delayed periods, accompanied by mood swings and a weepy disposition. It is suited for women who are emotionally sensitive and may experience scanty, late menses.
2. Sepia: Suitable for women who experience delayed periods along with mental and physical exhaustion, irritability, and apathy.
3. Lachesis: Useful when periods are delayed but the flow is profuse when they finally arrive, especially with sensitivity to tight clothing around the waist.
4. Calcarea carbonica: For women who are overweight, chilly, and easily fatigued, with delayed and scanty periods.
5. Natrum muriaticum: For women with emotional repression and delayed menses, often associated with anemia or weakness.

Next Steps:

It is important to explore the patient’s detailed history, including any associated symptoms (e.g., weight changes, hair growth, acne, mood changes), stress levels, and lifestyle factors. Blood tests to check thyroid function, prolactin levels, and possibly an ultrasound to rule out PCOS or other underlying conditions may be necessary.
