Signs of Protein Deficiency in Adults: What You Need to Know

Signs of Protein Deficiency in Adults: Key Symptoms

Think about this: You probably have a lot on your plate, like work, family, and maybe even a gym program. You pick foods that you think are excellent for you. But something isn’t right. Your hair is falling out, your skin is dry, and no matter how much sleep you get, you feel exhausted.

You might believe it’s simply stress or getting older, but it could be an indication that your body needs more protein. As someone who has spent years studying health and well-being, I know that people often forget about this important mineral. Let’s look at the signs of protein deficiency in adults, what causes them, and how you can get back on track.

Understanding of Signs of Protein Deficiency in Adults

Protein is like the construction crew of your body, building and repairing everything from muscles to hormones. It’s made up of amino acids, which are essential for:

  • Muscle growth and repair
  • Immune system function
  • Hormone and enzyme production
  • Healthy skin, hair, and nails
  • Bone strength
  • Energy production

When you don’t consume enough protein, your body is unable to perform essential functions, which can lead to various health issues. Kwashiorkor is a rare condition in developed countries, although even small protein shortages can create complications, especially for some ethnicities. Healthline says that even little deficiencies can cause symptoms that are easy to see.

Common Signs of Protein Deficiency in Adults

Your body is pretty adept at letting you know when something is amiss. Here are the most typical indicators that an adult isn’t getting enough protein, based on studies from reliable sources:

1. Tiredness and Weakness

Do you ever feel like you’re dragging through the day, even after a good night’s sleep? Protein is essential for energy and muscle health. Your muscles can’t heal properly, a sign of protein deficiency in adults, which can make you feel weak or tired.

This happens a lot in elderly people because they require extra protein to keep their muscles from getting weaker as they become older. Tiredness is one of the first indicators of not getting enough protein.

2. Hair loss and nails that break easily

Keratin is a protein that makes up your hair and nails. If you don’t get enough protein, your hair may become thinner and fall out, or your nails may break easily or get ridges, and that sparse hair and brittle nails are two signs that you don’t get enough protein. If your hairbrush is collecting more hair than usual, you might want to examine your diet.

3. Skin that is dry and flaky

Protein helps collagen and elastin, which keep your skin firm and moist. If you don’t consume enough protein, your skin may become dry and flaky

Protein helps collagen and elastin, which keep your skin firm and moist. If you don’t consume enough protein, your skin may become dry and flaky, increasing the likelihood of developing rashes and infections. WebMD says that having dry or flaky skin is a common sign that you’re not getting enough protein.

4. Losing Muscle

You need to take care of your muscles all the time, just like you do your house. Protein is what your body needs to fix things. Without it, your body will start to break down muscle tissue to get what it needs, which might make you weaker or lose muscle mass.

This is especially detrimental for elderly people since it can make sarcopenia, a normal aspect of ageing, worse; losing muscle is one of the most important signs of not getting enough protein.

5. Swelling (Oedema)

If you have low amounts of albumin, a protein in your blood, fluid might leak into tissues, which can make your legs, feet, or stomach bloat. Oedema is a sign of severe protein insufficiency. According to the Cleveland Clinic, oedema happens when there isn’t enough protein in the body to keep fluids in balance.

6. More likely to get infections

Antibodies that fight germs and viruses need protein to be made. If you don’t get enough of this, your immune system may not work as well, which makes you more susceptible to getting colds, the flu, or other infections.

7. Wounds heal slowly

Is your cut taking a long time to heal? Protein is necessary for making collagen and fixing tissues. If you don’t get enough protein, your wounds may take longer to heal, and you may be more likely to have infections.

8. Changes in Mood

Proteins break down into amino acids, which are used to make neurotransmitters like serotonin and dopamine that control mood. If you don’t receive enough of it, you can have mood swings, anxiety, or sadness.

9. Wanting and Hunger

Protein keeps you satiated longer than carbs or lipids do. You can feel hungry quickly after eating if you’re not getting enough, which can lead to cravings or overeating. NDTV says that a greater hunger and eating more calories can be signs that you don’t get enough protein. This could even cause you to gain weight without meaning to, as your body looks for less healthful meals to fill the gap.

10. Weak Bones

Protein is important for more than just muscles; it’s also important for bones. Collagen is a protein that gives bones their shape. If you don’t consume enough protein, your bones can become weaker, which makes them more likely to break. Studies say that not getting enough protein may raise the risk of fractures.

11. Liver with fat

In serious situations, not getting enough protein can cause fat to build up in the liver, which can cause inflammation or even damage to it. This happens more often in developing countries, but it’s still worth noticing.

12. Changes in weight

Not getting enough protein might make you lose weight (because you lose muscle) or gain weight (because you eat too much to make up for being hungry). According to the Harvard  Health, losing muscle can slow down your metabolism, which can make you gain weight even if you eat properly.
