Many things may cause low protein in blood. Malnutrition is a common cause. But issues like some autoimmune diseases, liver disease or kidney disease may cause hypoproteinemia. Treatment varies depending on the underlying cause.
However, excessive fat and protein are not conducive to the balance of absorption of substances in the body, which can easily lead to eating disorders that cause disorders in the intestinal microbiota, thus inducing diarrhea. And this may also be related to the lack or low activity of digestive enzymes.
Kwashiorkor and marasmus are the two main types of severe protein-energy undernutrition recognized by healthcare providers worldwide. The main difference between them is that kwashiorkor is predominantly a protein deficiency, while marasmus is a deficiency of all macronutrients — protein, carbohydrates and fats.
Management and Treatment
If your provider finds you have protein S deficiency but haven't had a blood clot, you are unlikely to require treatment except under certain circumstances. Anticoagulants in common use include heparin, warfarin, rivaroxaban, apixaban and dabigatran.
Signs of a protein deficiency
Feeling weak or hungry, since protein supplies energy and satisfies the appetite. Getting sick often without protein to boost the immune system. Mood changes or trouble thinking due to fluctuating blood sugar and protein's effect on the brain's neurotransmitters (which regulate mood)
Signs of low protein
Since nearly half of all protein in your body is stored in your muscles, a decline in muscle mass will be the most visible symptom of insufficient protein. But that's not the only red flag. Other symptoms of protein deficiency can include1: Brittle hair and nails.
Treating a protein deficiency includes eating more protein and/or improving your management of the medical condition that may be causing it.
Ways to Add Protein to Your Diet
Some milks—such as cow's milk and soy milk—are better than others at providing protein. Bone broth and some protein powders and shakes are great options for boosting your protein intake. Smoothie recipes can be enhanced with nut butter, silken tofu, or chia or flax seeds to boost the amount of protein.
Protein capsules can be made from a variety of sources, including whey, casein, soy, pea, or collagen. Consider any dietary restrictions or allergies you may have, and choose a source that aligns with your preferences and health needs. Check the label for how much protein is provided in each capsule or serving.
Mild protein deficiency typically shows improvement within 2-4 weeks of increased protein intake. Symptoms like fatigue and mild muscle weakness often resolve first, followed by improvements in hair and nail quality. Severe protein deficiency requires longer recovery periods, often 2-6 months for complete restoration.
Low protein in blood (hypoproteinemia) means that a blood test shows you have abnormally low levels of protein in your blood. Many things may cause low protein in blood. Malnutrition is a common cause. But issues like some autoimmune diseases, liver disease or kidney disease may cause hypoproteinemia.
Protein foods
Some food sources of dietary protein include: lean meats – beef, lamb, veal, pork, kangaroo. poultry – chicken, turkey, duck, emu, goose, bush birds. fish and seafood – fish, prawns, crab, lobster, mussels, oysters, scallops, clams.
A high-protein diet can cause constipation if it's low in fiber-containing foods. A well-planned high-protein diet that contains fiber-rich foods like vegetables, whole grains, and legumes can help promote regularity. Drinking enough fluids and getting enough physical activity also help with constipation.
Best protein powder alternatives
Several clinical trials have found that consuming more protein than the recommended dietary allowance not only reduces body weight (BW), but also enhances body composition by decreasing fat mass while preserving fat-free mass (FFM) in both low-calorie and standard-calorie diets.
Two eggs a day provide about 12-14 grams of high-quality protein, which is a great start but usually not enough for your entire daily requirement, especially if you're active; most adults need significantly more (around 46g for women, 56g for men), so you'll need to add other protein sources like meat, dairy, beans, or tofu to meet your goals, says the TODAY Show.

The "2-hour protein rule" refers to the idea that consuming protein within about two hours after exercise is crucial for muscle repair and growth, often suggesting a 20-30g serving to kickstart the recovery process, though modern science shows muscles stay receptive to protein for longer (up to 24 hours). While getting protein in this post-workout window (sometimes called the "anabolic window") is beneficial, especially if training fasted, total daily protein intake and evenly spaced meals are generally considered more important for overall muscle health, with a broader window of 4-6 hours for optimal synthesis after workouts.
The vegetable with the most protein is edamame (soybeans), offering around 18-19 grams per cooked cup, followed closely by other legumes like lentils and chickpeas, while even non-legumes like peas, spinach, and Brussels sprouts provide significant protein for plant-based diets, making legumes the top protein source among vegetables.
To get 100g of protein daily, focus on prioritizing protein at every meal (aiming for 30g+ per meal) by incorporating lean meats, fish, eggs, Greek yogurt, tofu, lentils, and beans, and use protein-rich snacks like nuts, seeds, or protein powder to fill gaps, planning ahead with batch cooking for easy access.
