Quick Answer
Hypoalbuminemia is a condition in which the blood does not contain enough albumin, a protein that keeps fluid in blood vessels and transports hormones and vitamins. Normal levels are 3.5 to 5.5 g/dL. Causes include heart failure and kidney or liver disease, and symptoms include leg swelling and fatigue. Shortness of breath or a racing heartbeat needs immediate emergency care. [1]
What the research says
Low albumin predicts death in heart failure. A meta-analysis of 9 studies with 16,763 heart failure patients found that hypoalbuminemia was linked to higher in-hospital mortality in acute heart failure (risk ratio 4.90, 95% CI 2.96-8.10) and higher long-term mortality (risk ratio 1.75, 95% CI 1.35-2.27). The authors note that randomized trials are still needed to show whether correcting albumin improves survival. (Peng et al., Biomarkers, 2019)
Low albumin before heart surgery signals a rougher recovery. In 20 studies with 22,553 cardiac surgery patients, low preoperative albumin was linked to higher long-term mortality (hazard ratio 1.95, 95% CI 1.54-2.48), about 1 extra day in intensive care, and about 3 extra days in hospital. (Xu et al., Surgery Today, 2023)
In older adults, inflammation matters as much as nutrition. A review found that age itself does not cause hypoalbuminemia, that low albumin predicts mortality in older people in the community, hospital, and care homes, and that inflammation (especially high IL-6 and TNF-alpha) is a main driver. In hip fracture patients, albumin below 38 g/L was linked to more post-surgery complications, especially infections. (Cabrerizo et al., Maturitas, 2015)
What is hypoalbuminemia?
Hypoalbuminemia is a state in which the blood has too little albumin. Albumin is a protein made by the liver that does two main jobs. It keeps fluid inside your blood vessels, and it carries substances such as hormones, enzymes, and vitamins through the body. [1] [4]
When albumin drops, the body has a harder time managing fluid. Fluid can leak into the tissues and cause visible swelling called edema. Hypoalbuminemia happens when the body does not make enough albumin or loses unusually large amounts of it in urine or stool. It is rarely a disease on its own and is usually a symptom of another health problem such as heart failure or kidney disease. [1]
What are the symptoms of hypoalbuminemia?
Because albumin helps keep fluid inside the blood vessels, many signs relate to fluid buildup. [1]
A surgical wound infection can also affect albumin levels. Signs of infection include fever and thick, cream-colored or white discharge from the surgery site. [1]
What causes hypoalbuminemia?
Hypoalbuminemia is a symptom of many different medical problems. It occurs when the body does not make enough albumin or loses it too quickly. [1]
Common underlying conditions
Category | Examples |
Organ dysfunction | Liver disease and cirrhosis, heart failure, and kidney disease including nephrotic syndrome. |
Metabolic and lifestyle | Diabetes, thyroid disease, alcohol use disorder, and malnutrition or a vitamin deficiency. |
Inflammatory states | Lupus, inflammatory bowel disease (IBD), and chronic inflammation. |
Infections | Infections of many kinds, including a surgical wound infection. |
Hospital-related risk factors
Some hospital treatments can increase the risk of low albumin. These include surgery, receiving fluids through an intravenous (IV) line, using a ventilator, or using a cardiopulmonary bypass machine. [1]
How is hypoalbuminemia diagnosed?
Providers use blood and urine tests to confirm low albumin and look for the cause. [1]
Albumin blood test: The most direct test. A normal level is 3.5 to 5.5 g/dL, and lower levels point to an underlying medical condition. [1]
Comprehensive metabolic panel (CMP): A blood test that measures 14 substances to check nutrient levels and liver and kidney function. [1]
Microalbuminuria test: A urine test that checks for albumin leaking into the urine. [1]
Urine albumin-creatinine ratio (uACR): A urine test that looks for signs of kidney damage. [1]
Treatment options for hypoalbuminemia
Treatment depends on why albumin is low. Managing the underlying condition may raise albumin levels and may manage or even cure the condition behind them. [1]
Clinical interventions
Blood pressure medication: Controlling blood pressure is part of treating the kidney disease or heart failure that can cause low albumin. [1]
Antibiotics: Used to treat infections. [1]
Anti-inflammatory medicine (NSAIDs): Used to manage inflammation, only as your doctor advises. NSAIDs such as ibuprofen can harm the kidneys and worsen heart failure and cirrhosis, so do not take them on your own if you have these conditions. [1]
Dialysis: One way to treat kidney disease when it is the cause. [1]
Nutritional support: Working with a nutritionist to plan heart-healthy meals or treat malnutrition. [1]
When to seek emergency care
Go to the emergency room or call 911 (or your local emergency number) right away if you have heart-related symptoms such as sudden shortness of breath, severe trouble breathing, or a rapid, racing heartbeat. Talk to a provider if you notice changes in urine color, unplanned weight loss, or swelling in your legs and feet. [1]
Conclusion
Hypoalbuminemia is an important clinical signal that something in the body needs attention. Your provider may treat it as a warning sign and run tests to find out why albumin is low. Finding and treating the cause is the key step, and it may also lift your albumin level. [1]

Frequently Asked Questions
Is hypoalbuminemia a type of cancer?
No. It can be a symptom or complication of some cancers or their treatments, but it is not a cancer itself.
Can I fix low albumin just by eating more protein?
Better nutrition helps when the cause is malnutrition, and a nutritionist can help plan your meals. Treatment depends on why your albumin is low, so talk to your doctor first. [1]
Does hypoalbuminemia cause weight gain?
Hypoalbuminemia can cause swelling in the feet and legs from fluid buildup. Losing weight without trying is also a reason to see a provider. [1]
Is low albumin the same as dehydration?
No. Albumin helps keep fluid inside the blood vessels, so low albumin is linked to swelling rather than simple fluid loss. [1]
Can stress cause hypoalbuminemia?
Everyday emotional stress is not a listed cause, but surgery and inflammation are. [1]
How long does it take to recover?
It depends on the underlying cause. Treating that condition may raise albumin levels, and chronic conditions need long-term management. [1]
Are there foods I should avoid?
It depends on the cause. A nutritionist can help plan meals that support heart health or manage malnutrition, and a provider can give you a specific plan. [1]
Can children get hypoalbuminemia?
Yes. Children can develop it, for example from kidney problems or malnutrition.
Is hypoalbuminemia contagious?
No. It is not infectious and does not spread from person to person.
Does low albumin affect my immune system?
Albumin itself is mainly for fluid balance and transport, but low albumin is a sign of illness such as inflammation or malnutrition, which can affect your overall health and your ability to fight infection. [4]
Can alcohol cause low albumin?
Yes. Alcohol use disorder is listed as a cause, and so is cirrhosis. [1]
What is the difference between albumin and globulin?
Both are blood proteins. Albumin mainly keeps fluid in the vessels and carries substances, while globulins include antibodies and proteins involved in immunity and clotting.
Can pregnancy cause hypoalbuminemia?
Mildly lower albumin can occur in normal pregnancy because blood volume increases, but very low levels should be checked by a doctor to look for complications such as preeclampsia.
Does exercise help with hypoalbuminemia?
Light activity may help circulation, but follow your doctor's advice, especially if you have heart or kidney disease.
Can I take supplements to raise my albumin?
Do not take protein supplements for this condition without medical supervision, because treatment depends on why your albumin is low. [1]
