Most chronic illnesses are due to oxidative stress and changes to tissue caused by low-grade inflammation.
Oxidative stress and low-grade inflammation have many causes, such as environmental toxins, poor diet, obesity, stress, and lack of sleep and exercise. These result in cellular damage.
If the situation is not rectified, it can lead to very serious illnesses. Both oxidative stress and low-grade inflammation can be treated with medication, the right diet, suitable supplements, and lifestyle changes.
