Your immune system is one of the most crucial systems in your body. It essentially directs certain cells around your body to fend off any foreign bodies that might have entered it, such as viruses and bacteria. It fights these illnesses in many ways, from using white blood cells to raising your body temperature, like when you have a fever, in order to kill off a virus. This is all great when you have a strong immune system, but if you have a weak one, it can lead to many problems for you.
Having a weak immune system is certainly something to worry about, so you need to know the signs to look out for to see if you might have a weaker than average immune system. There are different symptoms to look out for and different diseases that you might already have that will substantially lower your immune system.
The diseases that lower your immune system are well known and you’ll know that if you have these, you’ll have a reduced immunity. For example, HIV and AIDS are both autoimmune diseases, meaning that they damage and lower your immune system without some kind of treatment. Certain cancers will also lower your immunity, and you can be born with immunity deficiency disorders, which is something that you may have had to deal with your whole life.
One symptom that you have a weak immune system is that you’ll repeatedly and frequently get the same infections multiple times. For many people, infections are rare and typically only happen a few times throughout their lives. However, if you frequently contract things like pneumonia or strep throat, then you’re probably at a higher risk of a weakened immune system. Another very common symptom is frequent digestive problems. Things like frequent stomach aches, lack of appetite, or even diarrhea could mean that your immune system is weak. This is because a significant portion of your immune system is based around your digestive system, so if your digestive system is giving you a lot of problems, it could be that your immune system isn’t doing its job right.
For some people, low energy is a sign of a poor immune system. This is because your body is expending a lot of energy in keeping your immune system up to par, much more than other people typically would have to. If you’re getting enough sleep and still feeling tired all day, this might be the issue.
