Chronic Diseases
What is Chronic Diseases?
Chronic diseases are long-term health conditions that persist for months or years. These conditions often develop slowly and may worsen over time without proper management. Common chronic diseases include heart disease, cancer, diabetes, autoimmune disorders, and chronic inflammatory conditions.
Unlike acute illnesses that come on suddenly and resolve quickly, chronic diseases typically require ongoing medical attention. Many chronic diseases share common root causes such as inflammation, poor nutrition, and metabolic imbalances. Early detection through blood testing can help identify risk factors before symptoms appear.
The good news is that many chronic diseases can be prevented or managed through lifestyle changes. Understanding your blood biomarkers gives you insight into inflammation levels and other health indicators. This proactive approach helps you address problems at their source rather than just treating symptoms.
Symptoms
- Persistent fatigue that does not improve with rest
- Unexplained weight loss or weight gain
- Chronic pain or inflammation in joints or muscles
- Frequent infections or slow wound healing
- Digestive problems that last for weeks or months
- Shortness of breath or reduced exercise tolerance
- Skin changes such as rashes or discoloration
- Changes in appetite or energy levels
- Brain fog or difficulty concentrating
- Sleep disturbances or insomnia
Many people with developing chronic diseases have no obvious symptoms in the early stages. This is why regular blood testing is so important for catching problems before they progress. Your body may show changes in blood markers years before you feel sick.

Causes and risk factors
Chronic diseases develop from a combination of genetic, environmental, and lifestyle factors. Chronic inflammation is a common thread linking many conditions including heart disease, cancer, and autoimmune disorders. Poor diet, especially one high in processed foods and omega-6 fatty acids, promotes this harmful inflammation. Lack of physical activity, chronic stress, poor sleep, and exposure to toxins also contribute to disease development.
An imbalanced omega-6 to omega-3 ratio is a key driver of chronic inflammation. The typical Western diet contains far too many omega-6 fats from vegetable oils and processed foods. Other risk factors include obesity, smoking, excessive alcohol consumption, and family history. Many chronic diseases also involve problems with how your bone marrow produces blood cells, which can show up in reticulocyte counts.
How it's diagnosed
Chronic diseases are diagnosed through a combination of medical history, physical examination, and laboratory testing. Blood tests play a crucial role in identifying risk factors and detecting early signs of disease. Inflammatory markers, blood cell counts, and nutrient ratios can reveal problems before symptoms appear.
Rite Aid offers blood testing that measures key biomarkers related to chronic disease risk. The omega-6 to omega-3 ratio indicates your level of inflammatory stress. Absolute reticulocyte count shows how well your bone marrow is producing new red blood cells, which can be affected by chronic diseases like cancer or autoimmune conditions. Regular testing helps you track these markers over time and catch changes early.
Treatment options
- Adopt an anti-inflammatory diet rich in omega-3 fatty acids from fish, walnuts, and flaxseed
- Reduce omega-6 intake by limiting vegetable oils, fried foods, and processed snacks
- Exercise regularly with a mix of cardio and strength training activities
- Maintain a healthy weight through balanced nutrition and portion control
- Manage stress through meditation, yoga, or other relaxation techniques
- Get 7 to 9 hours of quality sleep each night
- Quit smoking and limit alcohol consumption
- Take prescribed medications as directed by your healthcare provider
- Work with a functional medicine doctor to address root causes
- Monitor your biomarkers regularly to track progress and adjust treatment

Frequently asked questions
The most common chronic diseases include heart disease, cancer, diabetes, chronic lung diseases, and autoimmune conditions. Alzheimer's disease, chronic kidney disease, and liver disease are also prevalent. Many of these conditions share similar risk factors such as inflammation, poor diet, and lack of exercise. Early detection through blood testing can help identify your risk for developing these conditions.
Yes, blood tests can reveal early warning signs of chronic diseases before symptoms appear. Markers like omega-6 to omega-3 ratio show your inflammatory status, which relates to many chronic conditions. Reticulocyte counts can indicate bone marrow problems associated with certain cancers or autoimmune diseases. Regular testing helps catch changes early when they are easier to address.
The omega-6 to omega-3 ratio measures the balance between two types of fatty acids in your blood. A high ratio indicates too much omega-6, which promotes inflammation throughout your body. This chronic inflammation increases your risk for heart disease, cancer, and autoimmune conditions. An ideal ratio is around 4:1 or lower, while many people have ratios of 15:1 or higher.
Reticulocytes are young red blood cells that show how actively your bone marrow is producing new cells. A low absolute reticulocyte count may indicate that chronic diseases like cancer or autoimmune disorders are affecting your bone marrow. It can also suggest nutritional deficiencies or bone marrow suppression. Your doctor will look at this marker alongside other tests to understand the underlying cause.
Eat more omega-3 rich foods like fatty fish, walnuts, flaxseed, and chia seeds. Reduce omega-6 intake by avoiding vegetable oils such as corn, soybean, and sunflower oil. Cook with olive oil or avocado oil instead. Limit processed and fried foods, which are typically high in omega-6 fats.
Some chronic diseases can be reversed or put into remission through lifestyle changes, especially when caught early. Type 2 diabetes, fatty liver disease, and early heart disease often respond well to diet and exercise interventions. Other chronic conditions like autoimmune diseases may not be fully reversible but can be managed effectively. The key is addressing root causes rather than just treating symptoms.
Most adults should get baseline blood work annually to screen for chronic disease risk factors. If you have existing risk factors or are managing a chronic condition, testing every 6 months helps track progress. Rite Aid offers 2 tests per year as part of the subscription, which is ideal for monitoring your inflammatory markers and blood cell production over time.
Diet and exercise are the most powerful tools for preventing chronic diseases. An anti-inflammatory diet with balanced omega fats reduces disease risk significantly. Regular physical activity improves metabolism, reduces inflammation, and supports immune function. Getting quality sleep and managing stress are also critical, as chronic stress and poor sleep drive inflammation and disease development.
Yes, several blood markers indicate chronic inflammation in your body. The omega-6 to omega-3 ratio is a key indicator of inflammatory balance. Other markers include C-reactive protein, which measures general inflammation levels. High inflammation over time damages tissues and organs, contributing to most chronic diseases.
Many autoimmune conditions are chronic diseases where the immune system attacks the body's own tissues. Conditions like rheumatoid arthritis, lupus, and inflammatory bowel disease involve ongoing inflammation and immune dysfunction. These diseases can affect bone marrow and blood cell production, which shows up in tests like reticulocyte counts. Both share common root causes including poor gut health, nutrient imbalances, and chronic inflammation.
