Q

Hirsutism is….

This occurs due to an excess of androgens (male hormones) or increased sensitivity of hair follicles to these hormones

Causes…(3)

Causes from medications…

A

When women grow facial, chest, and abdomen hair.

Polycystic Ovary Syndrome (PCOS) – The most common cause, leading to excess androgen production.

Cushing’s Syndrome – High cortisol levels can increase androgen levels.

Congenital Adrenal Hyperplasia (CAH) – A genetic disorder affecting adrenal hormone production.

Meds that cause hirsutism

Steroids, androgens, and some medications (e.g., danazol, minoxidil) can trigger excessive hair growth.

Hyperaldosteronism Renin levels.... Urine specific gravity.... Why? Hypokalemia Hypernatremia Metabolic alkalosis
Low renin in Primary Conns High renin in 2ndary. High renin is the cause the of hyperaldosteronism. RAAS Low specific gravity Hyperaldosteronism Excess Sodium Retention & Water Loss: Aldosterone increases sodium reabsorption in the kidneys, pulling water back into the bloodstream. This leads to expanded blood volume and increased blood pressure. The kidney compensates by excreting more water, leading to diluted urine with lower specific gravity.

Hypocalcemia C – Convulsions (seizures) ✅ A – Arrhythmias (prolonged QT, bradycardia) ✅ T – Tetany (muscle spasms, cramps) ✅ S – Spasms & Stridor (laryngospasms → airway risk!) ✅ Numb – Paresthesia (tingling in fingers, toes, lips)

Primary Hyperaldosteronism (AKA).... Cause..... Lab Findings: Aldosterone.... Renin.... K...... PH Balance.... Symptoms: Resistant hypertension (difficult to control with medication) Muscle weakness or cramps Fatigue Frequent urination Headaches
Conn’s Syndrome Overproduction of aldosterone due to an adrenal tumor or adrenal hyperplasia (both glands enlarged). High aldosterone Low renin (due to negative feedback) Hypokalemia (low potassium) Metabolic alkalosis
129
Secondary Hyperaldosteronism Cause: _________, often from conditions like: Renal artery stenosis (narrowing of kidney arteries) Congestive heart failure Cirrhosis Diuretics or excessive dehydration Lab Findings: Aldosterone..... Renin.....
Excess aldosterone due to high renin levels High aldosterone High renin (due to kidney sensing low blood volume)

Low cortisol levels during an acute episode. Elevated ACTH levels, since the pituitary gland is attempting to stimulate the adrenal glands. Electrolyte imbalances, including high potassium, low sodium, and low blood glucose. Low blood pressure and signs of dehydration. Name disease.... Name interventions....(4)
Addison Primary adrenal insufficiency Interventions Intravenous (IV) hydrocortisone (a synthetic form of cortisol) is given immediately to replace the missing cortisol and reverse the crisis. IV fluids (especially saline) to correct dehydration and electrolyte imbalances (e.g., correcting hyponatremia and hyperkalemia). Electrolyte correction, including glucose to treat hypoglycemia and sodium to correct low levels. Monitoring and supportive care, including managing any underlying infection (e.g., antibiotics if infection is suspected).

_____ acts as a counter-regulatory hormone to parathyroid hormone (PTH), which increases blood calcium levels.
