Symptoms of a Weakened Immune System


Picking Up a Common Cold a Lot


If you are someone that always seems to get a cold, then it could be a sign that your immune system is weak. Of course, everyone gets a cold from time to time. But getting them too often could mean that your body is unable to fight off the cold and keep your body protected. It’s worth keeping an eye on this. The same applies to things like coughs and sore throats. You should be aware of all these potential problems and how often they occur.


Excessive Tiredness


If you are tired a lot, it could be because your immune system is not doing its job properly. At the same time, not getting enough sleep can cause your immune system even more problems. So, you need be aware of both factors so that you can make sure that you get the sleep you need. If you are worried about your constant tiredness, see a doctor and get checked out. There are many things that could be causing your excessive tiredness.


Injuries Healing Slowly


Your immune system has to jump into action when you are injured or hurt in someway. Even something as simple as a small cut on your finger is a job for your immune system to fix. If you find that your injuries are healing very slowly, it could be because your immune system is experiencing difficulties. This is one of the most common symptoms of a weakened immune system, so beware of it.


Frequent Infections


Just like if you get colds too often, other types of infection occurring more than is normal could be a sign that your immune system is relatively poor. Infections have to be fought off and dealt with by your immune system, so when that doesn’t happen, they will progress faster and cause you more problems. If you are noticing this problem a lot, then it’s important to take action and get to the bottom of the problem.




Allergies are linked to your immune system. If you have lots of allergies, it could be because there are problems with your immune system. By definitely, an allergy occurs when there is something in particular, whether it’s peanuts or wheat, that your immune system can’t handle without a problem arising. Having one allergy is normal and not usually a sign of a problem with your immune system, but if you have more, there could be a problem.


Causes of a Weak Immune System

Poor Nutrition


Your diet affects so many things in your body. And your immune system is one of the things that you can damage by not having a healthy diet in place. You can find plenty of information below about some of the things that you should be including in your diet if you want to improve the performance of your immune system. Avoid foods that are fatty or high in salt. These things are always bad for you, and they’re not worth damaging your immune system over.




Not many people realise it, but stress is one of the things that is most damaging to your immune system. That’s why you should be aware of how much stress you’re under and putting your body through. Yes, it’s a mental issue, but it has physical implications. Stress and the hormones it releases have a direct impact on your immune system. So, tackle your stress problem and get it under control once and for all.


Not Enough Activity


A lack of physical activity is another thing that can end up damaging your immune system. This is what leads to you having excess weight on your body, which is not what you want. Your body will then be poorer in health generally, and you will have immune system problems later on. So, try to get a bit more active and ensure that you do what you can to shed the excess fat that you’re currently carrying.


Lack of Sleep


As briefly mentioned above, not getting enough sleep can also damage your immune system. Your body needs that sleep time to recover and refresh itself. If you starve your body of that sleep, it will not be good for you in the long-term. You should be aiming to do everything you can to allow your body the time it needs to get in shape and recover properly. Your immune system will thank you.




As we grow older, we become more likely to suffer immune system problems. This is just part of life and getting old. It’s why it’s always recommended that older people have a flu vaccination. It stops them from developing the flu and not being able to fight it off because of their weakened immune system. Just be aware of these changes as you get older and how you can deal with them.


Health Problems


There are some existing health problems that are linked to your immune system, and these can put extra strain on it. Diabetes is linked to a weakened immune system, and there are many other health problems out there that have a similar impact. Be sure to keep any health problems under control and take extra precautions to minimise your risk of infections.


What Are Immune System Disorders?


There are many disorders that originate with a problem in the immune system. For example, type 1 diabetes occurs when the body’s immune system attacks the insulin-producing cells in the pancreas. That’s why diabetics need to inject insulin. This is known as an autoimmune disease, and there are many other similar problems out there like this.


Even things like inflammatory bowel disease are immune disorders. In that specific example, the body attacks the lining of the bowel, which is what leads to the inflammation and the symptoms associated with inflammatory bowel disease. There are more immune system disorders out there than many people even realise.


How to Strengthen Your Immune System

Get Your Diet Right


If you want to strengthen your immune system, you need to make sure that you are consuming a healthy diet. In particular, you need to make sure that you are packing the right kinds of vitamins and antioxidants into your diet. If you can do that, then your body will be much healthier. And, most importantly, you will be able to be sure that your immune system will have the fuel it needs to function.


Make Sure You Get Enough Sleep


Getting more sleep is really important. Make sure that you get between 7 and 9 hours of sleep per night. And try to minimise any disruptions. You want to have a deep sleep that is continuous because this helps your body most. It will allow your immune system the time it needs to replenish and refresh. And you will then be in a much better position to fight off any infections and problems.


Ditch Bad Habits


If you are still clinging to the bad habits that are damaging to your health, you really need to ditch them. In particular, I’m talking smoking and drinking excessively. Both of these things can weaken your immune system You definitely need to give up smoking. And making sure that you drink less and in moderation will aid your immune system a lot too.


Pay Attention to Your Overall Health


Paying attention to your overall healthy can have a really big impact on how healthy you are able to be going forward. It matters a lot, and you shouldn’t turn a blind eye to any problems that you’re experiencing. If you notice any of the symptoms listed above, take action and talk to your doctor.


Low Immune System Tests


There are tests that can be carried out if you think your immune system might be weaker than it should be for whatever reason. It’s a simple blood test that can be carried out by your doctor. It will test how will the antibodies in your system attack threats. By testing them, it is possible to assess the strength of your immune system.


It’s a good idea to have this test carried out if you do have any concerns because you can then take action if there is a problem. As the information above illustrates, there are plenty of things you can do to improve your health and boost your immune system at the same time.
