Differential Diagnosis for Hair Loss in a 35-year-old Female
Single Most Likely Diagnosis
- Androgenetic Alopecia (Female Pattern Hair Loss): This is the most common cause of hair loss in women, characterized by thinning of hair over the mid-frontal scalp. It is often associated with hormonal changes and genetic predisposition.
Other Likely Diagnoses
- Telogen Effluvium: A condition that causes excessive hair shedding due to stress, hormonal changes, or medical conditions. It is reversible and often resolves on its own.
- Alopecia Areata: An autoimmune condition that leads to patchy hair loss. It can be triggered by stress, hormonal changes, or other autoimmune diseases.
- Thyroid Disorders: Both hypothyroidism and hyperthyroidism can cause hair loss due to the impact of thyroid hormones on hair growth.
- Polycystic Ovary Syndrome (PCOS): A hormonal disorder that can cause hair loss, acne, and irregular menstrual cycles.
Do Not Miss Diagnoses
- Lupus: A chronic autoimmune disease that can cause hair loss, skin rashes, and other systemic symptoms. Early diagnosis and treatment are crucial to prevent long-term damage.
- Thyroid Cancer: Although rare, thyroid cancer can cause hair loss, weight loss, and other systemic symptoms. Prompt diagnosis and treatment are essential.
- Pituitary Tumors: Tumors in the pituitary gland can disrupt hormone production, leading to hair loss, menstrual irregularities, and other symptoms.
Rare Diagnoses
- Trichotillomania: A psychological disorder characterized by compulsive hair pulling, leading to hair loss.
- Traction Alopecia: Hair loss caused by constant pulling or tension on the hair, often due to hairstyles like braids or ponytails.
- Loose Anagen Syndrome: A rare condition that causes hair to fall out easily due to a defect in the hair growth cycle.
- Hair loss due to Nutritional Deficiencies: Deficiencies in vitamins like biotin, vitamin D, or minerals like iron can cause hair loss.
