If your high blood pressure remains stubborn despite multiple medications, primary hyperaldosteronism (Conn’s syndrome) may be the underlying cause. This hormonal condition occurs when the adrenal glands overproduce aldosterone, forcing the body to retain sodium and waste potassium. The resulting "resistant hypertension" often presents with muscle cramps, fatigue, and heart palpitations.
Below, we explore the 2026 clinical landscape of this condition, including essential natural strategies for electrolyte balance, the hidden dangers of licorice supplements, and how to safely support your cardiovascular system alongside medical treatment.
Primary hyperaldosteronism is a medically serious endocrine condition. Natural strategies may support blood pressure and electrolyte balance, but they do not replace proper diagnosis (aldosterone/renin testing) and treatment. Seek medical care for severe hypertension, fainting, chest pain, weakness, or palpitations.
Conn’s syndrome occurs when one or both adrenal glands produce too much aldosterone, most commonly due to a benign adrenal adenoma or bilateral adrenal hyperplasia. The result is sodium retention (fluid expansion and high blood pressure) and potassium wasting.
Low potassium (hypokalemia) often develops gradually. Many people notice subtle “early warning” sensations before labs become critically abnormal:
These can be early clues that the aldosterone–potassium balance is shifting.
Glycyrrhizic acid (found in real licorice root and many licorice extracts) inhibits the enzyme that breaks down cortisol. This allows cortisol to activate the mineralocorticoid receptor, creating a state called pseudohyperaldosteronism. The result mimics aldosterone excess: higher blood pressure and lower potassium.
Action: Readers with Conn’s syndrome should avoid any supplement containing real licorice. Even “adrenal support” blends may contain licorice. If you use licorice for digestion, choose DGL (deglycyrrhizinated licorice) only—and verify the product truly removes glycyrrhizic acid.
Natural strategies can support blood pressure and symptoms, but they must be adjusted depending on whether you are untreated or on aldosterone-blocking medication.
Once you start spironolactone or eplerenone, your kidneys stop wasting potassium and begin retaining it. This flips the strategy:
Natural support must pivot 180 degrees once medical therapy begins to avoid dangerous hyperkalemia.
There is a metabolic loop many articles miss: high insulin (from frequent high-glycemic meals) drives potassium into cells, making blood potassium look even lower. This can trigger palpitations and muscle symptoms, even if total body potassium is marginal.
A low-glycemic diet (prioritizing vegetables, legumes, whole foods, adequate protein, and healthy fats) is a “secret weapon” for Conn’s patients. It helps prevent the insulin-driven potassium dip that can provoke heart palpitations and cramps.
Natural approaches can support blood pressure and symptoms, but they generally do not resolve an aldosterone-secreting tumor or adrenal hyperplasia. Targeted medical treatment is often required to reduce long-term cardiovascular risk.
High-glycemic meals raise insulin, which shifts potassium into cells—temporarily lowering blood levels and triggering palpitations or cramps in susceptible individuals.
