Signs You Might Have a Weakened Immune System

October 22, 2020 Updated: October 22, 2020

A healthy immune system can help you fight illness when you become infected with a harmful bacteria or virus. It might make battling certain illnesses easier or make it so you don’t even notice a symptom.

Certain warning signs can indicate a weakened immune system. Here are a few of them:

High Stress: Long-term stress may weaken the immune system by lowering lymphocyte levels. Lymphocytes are white blood cells your immune system uses to fight infections.

Always Fighting a Cold: It’s normal to go through 2 or 3 bouts of the cold per year. But if you’re getting them more frequently, and they are hanging around for more than 10 days, it’s a sign your immune system lacks strength.

Regular Indigestion: Frequent diarrhea, gas, or constipation could also be a sign of a compromised immune system. Studies are indicating roughly 70 percent of your immune system is located in your digestive tract. Digestive troubles could indicate a low level of healthy, beneficial bacteria, which may boost infection and inflammation risk.

Skin Wounds Stick Around: Little cuts, scrapes, or burns can also shed some light on immune strength. Your immune system is what causes these wounds to heal, so if they take an extended period to repair, your immune system isn’t functioning ideally.

Getting Sick Often: If you experience ear infections, pneumonia, bacterial sinusitis, or take more than two courses of antibiotics per year, it can indicate issues with immune health.

Fatigue: If you’re sleeping well but still feel fatigued, it could mean your immune system is working hard.

All of these could be signs of a weakened immune system. If you’re experiencing any of them, it is worth talking to your doctor.

You can also attempt natural immune-strengthening lifestyle measures such as:

  • Eating a balanced, nutrient-rich diet
  • Getting adequate sleep
  • Enjoying regular exercise
  • Washing your hands
  • Maintaining a healthy weight
  • Managing your stress
