Hypoaldosteronism (Hyporeninemic)
What is Hypoaldosteronism (Hyporeninemic)?
Hyporeninemic hypoaldosteronism is a condition where your body does not make enough aldosterone or renin. Aldosterone is a hormone that helps your kidneys balance potassium and sodium levels. Renin is an enzyme that signals your body to produce aldosterone. When both are low, potassium builds up in your blood.
This condition is most common in people with diabetes or chronic kidney disease. It usually develops slowly over time as kidney function declines. The result is persistently high potassium levels, also called hyperkalemia. While often mild, it requires careful monitoring and treatment.
Many people do not realize they have this condition until routine blood work reveals high potassium. Understanding your biomarker levels helps you catch problems early and protect your kidney health.
Symptoms
- Muscle weakness or fatigue
- Irregular heartbeat or palpitations
- Nausea or upset stomach
- Tingling or numbness in hands and feet
- Confusion or difficulty concentrating
- Chest pain or breathing difficulty in severe cases
Many people have no obvious symptoms in the early stages. High potassium is often discovered during routine blood testing before any warning signs appear.

Causes and risk factors
The most common cause is damage to the part of the kidney that produces renin. Diabetes is the leading risk factor, especially when blood sugar is not well controlled over many years. Chronic kidney disease from any cause can also damage the cells that make renin. Other causes include certain autoimmune conditions, prolonged use of NSAIDs like ibuprofen, and aging.
Risk factors include having type 1 or type 2 diabetes, kidney disease, being over age 60, and taking medications that affect potassium balance. ACE inhibitors, ARBs, and potassium-sparing diuretics can worsen hyperkalemia in people with this condition. A diet very high in potassium may also contribute to elevated levels.
How it's diagnosed
Diagnosis requires blood tests to measure potassium, renin, and aldosterone levels. High potassium with low renin and low aldosterone points to hyporeninemic hypoaldosteronism. Your doctor may also check kidney function tests and blood sugar to look for underlying diabetes or kidney disease.
Rite Aid offers testing for potassium levels through our flagship panel at Quest Diagnostics locations nationwide. Regular monitoring helps you track changes over time and adjust treatment as needed. If initial results show high potassium, your doctor may order additional hormone tests to confirm the diagnosis.
Treatment options
- Reduce dietary potassium by limiting bananas, oranges, potatoes, tomatoes, and salt substitutes
- Review medications with your doctor, especially NSAIDs and blood pressure drugs that raise potassium
- Take potassium-binding medications like sodium polystyrene sulfonate or patiromer if prescribed
- Use mineralocorticoid replacement therapy with fludrocortisone in some cases
- Control blood sugar levels if you have diabetes to slow kidney damage
- Monitor kidney function regularly and adjust treatment as needed
- Stay hydrated and maintain a healthy weight

Frequently asked questions
Hyporeninemic hypoaldosteronism is a hormone condition where your body makes too little renin and aldosterone. These hormones help control potassium balance. When they are low, potassium builds up in your blood, which can affect heart and muscle function.
The most common cause is kidney damage from diabetes or chronic kidney disease. The damaged kidneys cannot produce enough renin to signal aldosterone production. Other causes include certain medications, autoimmune diseases, and natural aging of kidney tissue.
Symptoms include muscle weakness, fatigue, irregular heartbeat, nausea, and tingling sensations. Many people have no symptoms at all in early stages. Severe cases can cause dangerous heart rhythm problems that require immediate medical attention.
Diagnosis requires blood tests showing high potassium with low renin and aldosterone levels. Your doctor will also check kidney function and blood sugar. Regular potassium monitoring helps track the condition over time and guide treatment decisions.
There is no cure, but the condition can be managed effectively with diet, medication, and lifestyle changes. Treatment focuses on keeping potassium levels in a safe range. Managing underlying diabetes or kidney disease can prevent the condition from getting worse.
Limit high-potassium foods like bananas, oranges, potatoes, tomatoes, spinach, and dried fruits. Avoid salt substitutes, which contain potassium chloride instead of sodium. Your doctor or dietitian can provide a detailed list based on your specific potassium levels.
Potassium-binding drugs like patiromer or sodium polystyrene sulfonate help remove excess potassium. Some people need fludrocortisone to replace missing aldosterone. Your doctor may also adjust blood pressure medications that can raise potassium levels.
High potassium can be dangerous if left untreated, especially for your heart rhythm. Most cases are mild and manageable with proper monitoring and treatment. Severe hyperkalemia requires immediate medical care to prevent life-threatening heart problems.
Testing frequency depends on how high your potassium is and what treatments you are using. Many people need testing every few weeks initially, then every few months once stable. Talk to your doctor about the right schedule for your situation.
Yes, diabetes is the most common cause of this condition. High blood sugar over time damages the kidney cells that produce renin. Good blood sugar control helps protect your kidneys and may prevent or slow the development of hyporeninemic hypoaldosteronism.
