Long-term exposure to stressful situations disrupts the body's natural defense system against antioxidants resulting in increased levels of oxidative stress.
The presence of chronic inflammation often accompanies conditions such as obesity, autoimmune diseases, and infections, contributing to elevated levels of oxidative stress.
The ageing process naturally brings about a decline in antioxidant capacity within our bodies. Rendering us more vulnerable to experiencing oxidative stress.
To comprehend how oxidative stress adversely affects our general health and well-being. It is important that we delve into its impact on our body's cells and organs:
When subjected to high levels of oxidative stress diverse components within cells such as proteins, lipids, and DNA face potential harm. This injury may greatly impair cell functioning while disrupting vital biological procedures.
Mitochondria play a pivotal role in energy production within cells but are immensely vulnerable to oxidative stress. Consequently, Cellular energy output decreases considerably due to compromised mitochondrial integrity translating into impaired cellular function alongside extensive tissue damage.
The presence of unchecked levels of oxidative distress precipitates a sequence of inflammatory reactions across different bodily systems. Prolonged inflammation directly resulting from excessive oxidation has been implicated extensively in the development and secondary progress of multiple diseases such as cardiovascular diseases, diabetes, and neurodegenerative conditions.
Under oxidative stress. DNA structure can sustain significant damage. Therefore, increasing the risk of strand termination, mutations and instability. This heightened vulnerability considerably amplifies the possibility of cancer development.
There is a well-documented correlation between oxidative stress and ageing. Oxidative stress accumulation over time accelerates cellular ageing processes and subsequently contributes to diseases typically representative of advancing age.
If the body's endogenous antioxidant defenses fail to counter excessive oxidative stress effectively it may lead to organ dysfunction. Organs particularly vulnerable to such oxidative damage are those including but not limited to the heart, liver, brain, and kidneys, which when compromised can impede their regular functioning mechanisms.
Oxidative stress testing is an important tool in assessing levels of oxidative stress in the body and understanding the extent of oxidative damage. Here we will explore some common methods and techniques used in this type of testing.
Biomarkers are specific molecules or substances that indicate the presence or severity of oxidative stress. Several commonly measured biomarkers include reactive oxygen species (ROS) levels, lipid peroxidation products such as malondialdehyde (MDA) and antioxidant enzyme activity like superoxide dismutase (SOD) and catalase.
TAC assays provide an overall measure of the body's ability to counteract oxidative stress by assessing the overall antioxidant capacity of a biological sample.
These tests assess the extent of DNA damage caused by oxidative stress. Often measuring levels of 8 hydroxy 2'-deoxyguanosine (8 OHdG).
This index combines measurements from various oxidative stress biomarkers to provide an overall assessment of oxidative stress levels.
Advanced imaging techniques such as positron emission tomography (PET) and magnetic resonance imaging (MRI) can visually and quantitatively analyze oxidative stress-related changes in specific organs or tissues.
Cell-based assays evaluate oxidative stress levels by measuring changes in cellular functions or markers of oxidative damage.
Biomarkers hold significant importance in evaluating levels of oxidative stress while also offering valuable insights into our health status. Through these quantifiable indicators. Healthcare professionals can assess the degree of oxidative damage experienced while effectively monitoring intervention outcomes designed specifically for addressing oxidative stress.
