Acute and chronic inflammation

Understanding inflammation

Inflammation is part of your body’s immune response to harmful substances. Infections, wounds, and damage to any tissue would not be able to heal without an inflammatory response. There are two types of inflammation: acute and chronic inflammation.

Acute inflammation

Acute inflammation comes on very quickly and usually resolves in two weeks or less. During this process, your body responds to harmful substances, repairs damage to cells and carries away dead cells. It results in symptoms like:  

  • redness
  • swelling
  • heat
  • pain

Examples of conditions that involve acute inflammation include acute bronchitis, a sore throat from a cold or flu or an infected ingrown toenail.

Chronic inflammation

Chronic inflammation is a slower and generally less severe form of inflammation. It can happen when your body can’t remove the harmful substance or heal an injury and this means your body stays in a state of inflammation for several months or even years. It can also happen if the harmful substance is gone but the body still stays in inflammatory state.

Some of the symptoms of chronic inflammation can include:

  • body pain
  • constant fatigue and insomnia
  • depression, anxiety and mood disorders
  • problems with digestion
  • weight gain
  • frequent infections.

Research suggests there is a link between chronic inflammation and some chronic diseases. These chronic diseases include cardiovascular disease, chronic kidney disease, and type 2 diabetes.

5 risk factors for chronic inflammation

  1. Obesity

    Studies have found that when someone is obese, their body is more likely to be in a state of inflammation. If you’re in this category, it’s a good idea to start looking at weight loss strategies.

  2. Diet

    If your diet is high in saturated fat, trans fat, or refined sugar, you’re more likely to have higher levels of inflammatory markers in the body. On the other hand, a 2018 study found that a diet similar to a traditional Mediterranean diet can reduce the level of inflammatory markers in your body.

  3. Stress and sleep disorders

    If you’re experiencing physical or emotional stress, you’re more likely to be in a state of inflammation. Stress can also lead to sleep disorders and there is a link between irregular sleep patterns and an increase in inflammation in the body.

  4. Smoking

    Smoking, or breathing in second-hand smoke, encourages an inflammatory response. Often the immune system overcompensates for the intake of these toxins, which can mean that the white blood cells - rather than healing the damaged tissue - work on the offensive. This increases the risk of lung cancer.

  5. Age

    The older you are, the more likely you are to have higher levels of inflammatory molecules. This may be due to free radical accumulation over and other age-related risk factors like and increase in visceral fat. 

6 ways you can fight inflammation

  1. Eat your veggies and fruit

    A diet rich in fruit and vegetables is one of the best ways to avoid chronic inflammation. Vegetables are full of anti-inflammatory nutrients, including magnesium, carotenoids, antioxidants and lycopene.

    The following vegetables and fruits are particularly anti-inflammatory:

    • tomatoes
    • olive oil
    • green leafy vegetables like spinach and kale
    • fruits such as strawberries, blueberries.
  2. Limit these foods

    The following foods have been found to increase inflammation in the body:

    • refined carbohydrates like white bread and pastries
    • fried foods
    • soda
    • red meat and processed meats
    • margarine, shortening and lard.
  3. Eat more fatty fish

    Foods rich in Omega-3 fatty acids such as can anti-inflammatory. You can try adding fatty fish such as salmon, mackerel, tuna or sardines to your diet.

  4. Exercise regularly

    Regardless of your weight, regular exercise can help prevent chronic inflammation and reduce your risk of chronic disease.

  5. Get more sleep

    It’s important to make sure you’re getting enough sleep. If you’re not getting adequate sleep, you’re likely to be a higher risk of inflammation. Read more about tips to getting a good night’s sleep

  6. Relax

    People with anxiety or depression can lower their inflammation markers simply by getting treatment. Lowering stress of any kind is going to lower your risk of inflammation.

I joined as a CBHS member in 1978. Through many health events and challenges CBHS has always been there for me and my family. Their exceptional service over this time has always been appreciated.

I've not long joined CBHS from another fund, but so far I've been impressed by the super helpful and friendly staff, the higher claim limits and rebates at a very competitive premium, and how easy it is to lodge manual claims through the app. Thanks CBHS - you've won me over! 😃

What Our Members Think

I have been with CBHS since I began at CBA 15 years ago...Now I have three beautiful children, one who has a disability. Our top extras cover has been really essential for his early intervention. I do love the ease of claiming online.

What Our Members Think

I am relatively new to CBHS and am loving it already. I worked for a CBA subsidiary a long time ago but was still eligible to join. So much better that the for-profit funds - our premium is only a little more and we pay a lower co-contribution and get great benefits. I am loving the massage rebate for my partner and gym rebate for me!

What Our Members Think

Love CBHS as I never have to doubt that they've got my back when I need it. Been through other insurers who have limited options or limits, yet cost the same or more.
