Hypoalbuminemia
What is Hypoalbuminemia?
Hypoalbuminemia is a condition where your blood has low levels of albumin. Albumin is the most abundant protein in your blood. It helps keep fluid in your bloodstream instead of leaking into your tissues. It also carries hormones, vitamins, and medications throughout your body.
When albumin levels drop too low, you may experience swelling, fatigue, and other problems. Your liver makes all the albumin your body needs. Low levels often point to liver disease, kidney problems, or malnutrition. In some cases, inflammation or severe infections can lower albumin temporarily.
Normal albumin levels range from 3.5 to 5.5 grams per deciliter. Levels below 3.5 indicate hypoalbuminemia. The lower your albumin, the more serious the underlying condition may be. Early detection through blood testing helps identify root causes before symptoms become severe.
Symptoms
- Swelling in your legs, ankles, feet, or abdomen, also called edema
- Fatigue and weakness that does not improve with rest
- Loss of muscle mass, especially in your arms and legs
- Weight changes, either loss or gain from fluid buildup
- Yellowing of skin or eyes if liver disease is the cause
- Foamy or bubbly urine when kidney problems are present
- Difficulty healing from wounds or infections
- Diarrhea or digestive issues when malnutrition is involved
Many people have no symptoms in the early stages of hypoalbuminemia. Symptoms usually appear when albumin levels drop significantly or when the underlying condition worsens.

Causes and risk factors
Your liver produces all the albumin in your blood. Liver diseases like cirrhosis, hepatitis, or fatty liver disease can reduce albumin production. Kidney disease, especially nephrotic syndrome, causes your body to lose albumin through urine. Inflammatory bowel disease or protein-losing enteropathy can cause albumin loss through your digestive system. Severe malnutrition or extremely low protein intake prevents your liver from making enough albumin.
Other risk factors include severe burns, major surgery, sepsis, and chronic inflammation. Cancer, heart failure, and thyroid disorders can also lower albumin levels. Older adults and people with chronic diseases face higher risk. Long hospital stays and critical illness often lead to temporary low albumin levels.
How it's diagnosed
Hypoalbuminemia is diagnosed through a simple blood test that measures albumin levels. A total protein test is often ordered at the same time. Albumin makes up 50 to 60 percent of total protein in your blood. These tests help identify if low protein is specifically due to low albumin. Rite Aid offers testing for albumin and total protein as part of our flagship blood panel.
If your albumin is low, your doctor will order additional tests to find the cause. These may include liver function tests, kidney function tests, and urine protein measurements. Your doctor will also review your medical history, diet, and medications. Finding the root cause is essential for proper treatment.
Treatment options
- Treat the underlying condition causing low albumin, such as liver or kidney disease
- Increase protein intake through foods like eggs, fish, chicken, beans, and dairy
- Work with a registered dietitian to create a nutrition plan that supports albumin production
- Take medications to manage liver disease, kidney disease, or inflammation as prescribed
- Reduce alcohol intake to protect liver function and albumin production
- Manage fluid retention with diuretics if swelling is severe
- Address infections promptly, as they can lower albumin levels
- Monitor albumin levels regularly through blood tests to track progress
- Consider albumin infusions in severe cases, though this is a temporary solution

Frequently asked questions
Low albumin means your blood has less than 3.5 grams per deciliter of this essential protein. It often signals liver disease, kidney problems, malnutrition, or chronic inflammation. Your doctor will order additional tests to find the specific cause. Early detection helps prevent complications like swelling and muscle loss.
The most common symptom is swelling in your legs, ankles, feet, or abdomen. You may also feel tired and weak despite getting rest. Many people notice muscle loss or weight changes. Some people have no symptoms until albumin levels become very low.
Yes, severe malnutrition or very low protein intake can cause hypoalbuminemia. Your liver needs protein from food to make albumin. However, most cases result from liver disease, kidney disease, or inflammation rather than diet alone. Eating more protein helps if malnutrition is the cause.
Treatment focuses on addressing the underlying cause. This may include medications for liver or kidney disease, increased protein intake, and managing inflammation. Your doctor may prescribe diuretics to reduce swelling. In severe cases, albumin infusions provide temporary relief while the root cause is treated.
High-protein foods help your liver produce albumin. Good choices include eggs, chicken, fish, lean beef, beans, lentils, Greek yogurt, and cottage cheese. Aim for protein at every meal. Work with a dietitian to ensure you get enough protein without overloading your kidneys or liver.
Hypoalbuminemia can be serious because it often signals significant liver, kidney, or nutritional problems. The lower your albumin, the higher your risk for complications. These include severe swelling, infections, and poor wound healing. Early detection and treatment of the root cause can prevent serious outcomes.
Testing frequency depends on your underlying condition. If you have liver or kidney disease, your doctor may test albumin every 3 to 6 months. If you are recovering from illness or malnutrition, more frequent testing helps track progress. People without known conditions should test albumin as part of routine health screenings.
Yes, liver disease is one of the most common causes of hypoalbuminemia. Your liver makes all the albumin in your body. Conditions like cirrhosis, hepatitis, and fatty liver disease reduce albumin production. Treating liver disease and avoiding alcohol can help restore albumin levels over time.
Albumin is one specific protein that makes up 50 to 60 percent of total protein in your blood. Total protein measures all proteins combined, including albumin and globulins. Both tests are often ordered together. Low total protein usually means low albumin, but individual results guide diagnosis.
Yes, hypoalbuminemia can often be reversed if the underlying cause is treated. Improving nutrition, managing liver or kidney disease, and reducing inflammation can restore normal levels. Recovery time varies based on the cause and severity. Regular blood testing helps monitor your progress and adjust treatment as needed.
