What is Calcium Buildup?
Calcium buildup, or calcification, is the accumulation of calcium salts in the soft tissues of the body, including arteries, joints, and organs. While calcium is vital for bones and teeth, its misplacement in soft tissues can be a sign of underlying health issues. This process is distinct from the normal bone remodeling that occurs throughout life.
The Role of Age and Calcium
Age is a major non-modifiable risk factor for calcification. As we get older, our tissues lose elasticity and become more susceptible to damage and inflammation. This creates an environment where calcium deposits are more likely to form. While some level of arterial hardening is considered normal with age, excessive calcification can lead to serious health problems.
Arterial Calcification: A Timeline
Calcification of the arteries is a significant indicator of cardiovascular risk. It typically occurs as part of atherosclerosis, where plaque (fat and cholesterol) builds up in the artery walls.
- Beginning in Young Adulthood (20s-30s): The initial stages of calcification can be microscopic and go unnoticed. Studies have shown that microcalcification in the intimal layer of arteries can begin in a person's 20s, but these small deposits are rarely detected through standard imaging.
- Acceleration in Mid-Adulthood (40s-60s): Detectable arterial calcification often starts to appear on imaging scans in adults over 40. The process generally accelerates for men after age 55 and for women after age 65, partly due to the protective effects of estrogen in women before menopause.
- High Prevalence in Older Adults (70+): The prevalence of coronary artery calcification increases dramatically with age. For instance, studies show that by age 70, over 90% of men and 67% of women have some degree of coronary artery calcification.
Joint and Tendon Calcification
Calcification isn't limited to the cardiovascular system; it can also affect joints and tendons, a condition known as calcific tendinitis.
- Typical Age Range (30-60): This condition most commonly affects individuals between the ages of 30 and 60. It is characterized by the formation of calcium deposits in a tendon, most frequently the rotator cuff in the shoulder.
- No Obvious Cause: Unlike arterial calcification, the exact cause of calcific tendinitis is often unknown, though it is more common in women than men. Symptoms can range from severe pain to no symptoms at all.
Other Types of Calcification
Calcification can occur in various other parts of the body due to different causes, and at varying ages.
- Breast Calcification: Often found during routine mammograms, these small calcium deposits are usually benign, though a cluster can be a sign of cancer. The incidence often increases with age.
- Kidney Calcification (Nephrocalcinosis): This condition involves calcium deposits in the kidneys and can be related to calcium metabolism disorders or chronic kidney disease. While often associated with health issues, it is not strictly age-dependent.
- Brain Calcification: Rare genetic conditions, chronic inflammation, or infections can cause calcification in brain blood vessels or tissue, sometimes leading to movement disorders. This can occur across different age groups.
Understanding the Risk Factors Beyond Age
While age is a key factor, it is by no means the only one. Several other elements influence your risk of developing calcification.
Lifestyle Risk Factors
- High Cholesterol: High levels of bad cholesterol (LDL) are a major driver of atherosclerosis, which leads to arterial calcification.
- High Blood Pressure (Hypertension): High blood pressure damages artery walls, making them more susceptible to calcium deposits.
- Diabetes: Poorly managed glucose levels contribute to inflammation and damage throughout the body, including the vascular system.
- Smoking: Tobacco use is a significant risk factor for cardiovascular disease and accelerates arterial calcification.
- Sedentary Lifestyle: Lack of physical activity contributes to poor cardiovascular health and increased risk factors like high cholesterol and obesity.
Genetic and Other Health Factors
- Family History: A family history of early cardiovascular disease or calcification increases your personal risk.
- Genetics: Specific genetic variations can influence calcium metabolism and inflammation responses.
- Chronic Kidney Disease (CKD): CKD severely affects calcium and phosphate metabolism, leading to increased risk of calcification.
- Hormone Levels: The decline in estrogen after menopause accelerates bone loss and can increase the risk of calcification in women.
Prevention and Management Strategies
Preventing calcium buildup involves a proactive approach to managing your health. While you can't stop the natural aging process, you can control many of the risk factors.
- Maintain a Healthy Lifestyle: Regular exercise, a balanced diet, and maintaining a healthy weight are foundational. A diet rich in fruits, vegetables, and whole grains, and low in processed foods and saturated fats, supports overall health.
- Monitor Your Health: Regular check-ups with your doctor are essential, especially as you enter your 40s and beyond. Monitoring cholesterol, blood pressure, and blood sugar levels is vital.
- Regular Screenings: A coronary artery calcium (CAC) score is a non-invasive imaging test that can detect calcium deposits in the heart's arteries. It's often recommended for individuals between 40 and 75 with risk factors but no symptoms.
- Manage Underlying Conditions: Effectively treating conditions like diabetes, high blood pressure, and CKD is critical for slowing down calcification.
Comparison of Common Calcification Types
| Feature | Arterial Calcification | Calcific Tendonitis (Joint/Tendon) |
|---|---|---|
| Primary Location | Arteries (Coronary, etc.) | Tendons (Shoulder, etc.) |
| Common Age Range | Starts in 20s/30s, accelerates >40 | Most frequent 30-60 |
| Primary Cause | Atherosclerosis, inflammation, genetics, age | Unknown, possibly related to low oxygen |
| Main Symptoms | Often asymptomatic, but can lead to angina, heart attack, stroke | Acute or chronic pain, especially with movement |
| Key Risk Factors | High cholesterol, hypertension, diabetes, smoking | Genetics, gender (more common in women) |
| Typical Treatment | Lifestyle changes, statins, BP meds, aspirin, possible surgery | Cortisone injections, anti-inflammatory meds, physical therapy, surgery |
The Role of Diet: Myth vs. Fact
Many people mistakenly believe that eating a high-calcium diet causes calcium buildup. This is a myth. The Cleveland Clinic clarifies that a diet high in calcium does not cause calcification. The body tightly regulates blood calcium levels. Issues arise when calcium is deposited in the wrong places due to other factors like inflammation or underlying disease, not because of dietary intake.
- Instead of reducing dietary calcium, the focus should be on maintaining overall heart and metabolic health.
- In fact, adequate calcium intake is essential for maintaining strong bones and preventing conditions like osteoporosis. Excess calcium intake, particularly from supplements, is not recommended unless advised by a doctor.

Conclusion: A Lifelong Journey
Ultimately, there is no single answer to at what age do you get calcium build up. It's a progressive process that often starts subtly in young adulthood and becomes more prevalent and detectable with advancing age. While genetics and aging play a role, understanding and managing lifestyle-related risk factors, such as blood pressure, cholesterol, and diet, are your most powerful tools. Taking proactive steps early in life can significantly impact the health of your arteries and joints as you age, helping to prevent the complications associated with excessive calcium deposits.
