The Unexpected Link Between Biking and PSA Blood Tests
Written on
Understanding PSA Levels and Their Implications
During a recent visit to my grandmother, she shared an intriguing tale about her friend, Dave. An enthusiastic mountain biker, Dave often spends hours riding his bike. A few weeks ago, he visited his doctor for a PSA blood test, which returned abnormal results. Fortunately, there was a specific reason behind his elevated PSA levels.
At first, I was unfamiliar with the term PSA, which stands for prostate-specific antigen. This protein is produced by the prostate glands, with some of it leaking into the bloodstream. The levels can vary based on age and prostate health. Both cancerous and non-cancerous prostate tissues can produce PSA, making the test useful for detecting potential prostate cancer.
Currently, the UK does not have a nationwide PSA screening program. This is mainly because, as demonstrated in Dave's case, the PSA test is not always reliable for diagnosing prostate cancer. There are various other factors that can lead to increased PSA levels, such as an enlarged prostate, prostatitis, or urinary tract infections (UTIs). Studies indicate that 75% of men with elevated PSA levels do not actually have cancer, while about 1 in 7 men with prostate cancer may have normal PSA results.
Returning to Dave's situation, a normal PSA level is considered to be 3 ng/ml, while his test indicated a PSA level of 13 ng/ml—significantly above the normal range. Given Dave's passion for biking, many readers may know that bike seats are not particularly supportive in that area. Consequently, extended periods on these seats can lead to prostate inflammation.
A 2013 study published in PLOS One, titled "Long Distance Bicycle Riding Causes Prostate-Specific Antigen to Increase in Men Aged 50 Years and Over," found that cycling can cause an average 9.5% rise in PSA levels. For someone like Dave, who rides for long stretches, the increase in his PSA levels was not a sign of prostate cancer but a result of prolonged saddle time.
Luckily, Dave's doctor was aware of his biking habits and understood the connection between cycling and elevated PSA results. He advised Dave to refrain from biking for a week and return for a follow-up test. Sure enough, the subsequent test showed his PSA levels had returned to normal, around 3 ng/ml.
Dave's case highlights how certain medical scenarios may not be straightforward, necessitating a comprehensive analysis before reaching a diagnosis. It underscores the necessity for doctors to be well-informed about such unexpected correlations—similar to insights shared in recent publications on health conditions like G6PD Deficiency exacerbated by certain foods.
Strategies for Bikers to Manage PSA Levels
Bikers can adopt several measures to help reduce the increase in PSA levels. Using a male bike seat with better cushioning can alleviate pressure on the prostate. Tilting the bike seat forward can offer similar benefits. Additionally, regularly standing on the pedals allows for a change in position, which can help. And of course, wearing a helmet remains crucial for safety!
