Your body at 40 is different from your body at 25, and the health risks you face begin to shift in meaningful ways. The good news? Most of the serious conditions that affect men after 40 are <strong>preventable, treatable, or manageable<\/strong> \u2014 if they&#8217;re caught early.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This guide outlines the key screenings and health markers every man should be tracking from his 40s onward, with specific guidance for those living in Japan.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Why 40 Is the Turning Point<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Several biological shifts converge around age 40:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Testosterone decline accelerates:<\/strong> While the drop begins around 30, many men first notice symptoms \u2014 fatigue, weight gain, mood changes \u2014 in their 40s.<\/li>\n<li><strong>Cardiovascular risk increases:<\/strong> Atherosclerosis (arterial plaque buildup) is a decades-long process that starts producing clinical consequences around this age.<\/li>\n<li><strong>Cancer screening becomes relevant:<\/strong> The risk of prostate, colon, and other cancers begins to rise significantly.<\/li>\n<li><strong>Metabolic changes:<\/strong> Insulin resistance, visceral fat accumulation, and metabolic syndrome become more prevalent.<\/li>\n<li><strong>Bone density starts declining:<\/strong> Though discussed less than in women, men lose bone density too \u2014 increasing fracture risk later in life.<\/li>\n<\/ul>\n\n\n\n<h2 class=\"wp-block-heading\">The Essential Checkup Checklist<\/h2>\n\n\n\n<h3 class=\"wp-block-heading\">1. Testosterone and Hormone Panel<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why:<\/strong> Low testosterone affects an estimated 20\u201330% of men over 40. Symptoms overlap with depression, burnout, and general aging, making it easy to overlook.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What&#8217;s tested:<\/strong> Total testosterone, free testosterone, LH, SHBG. Additional markers like DHEA-S and estradiol may be included.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Frequency:<\/strong> Baseline at 40, then every 1\u20132 years if asymptomatic. More frequently if symptoms are present or you&#8217;re on treatment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>In Japan:<\/strong> Available at urology clinics, endocrinologists, and English-speaking general practice clinics. Insurance covers testing when symptoms are documented.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">2. PSA (Prostate-Specific Antigen)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why:<\/strong> Prostate cancer is the most common cancer in men globally and the most common cancer diagnosed in foreign men living in Japan. Early detection dramatically improves outcomes.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What&#8217;s tested:<\/strong> A simple blood test measuring PSA levels. Elevated levels may indicate prostate enlargement, inflammation, or cancer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Frequency:<\/strong> Baseline at 40 (especially if there&#8217;s a family history), then annually or biennially from age 50. Earlier and more frequent screening for men of African descent or those with a first-degree relative diagnosed with prostate cancer.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>In Japan:<\/strong> PSA testing is widely available and often included in comprehensive health checks (<em>ningen dock<\/em>). Cost is typically \u00a51,000\u20133,000.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">3. Blood Pressure<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why:<\/strong> Hypertension is called the &#8220;silent killer&#8221; because it often produces no symptoms until a serious event (heart attack, stroke) occurs. Prevalence increases markedly after 40.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Target:<\/strong> Below 130\/80 mmHg (current guidelines). Sustained readings above 140\/90 typically warrant treatment.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Frequency:<\/strong> At every doctor visit, or self-monitored at home weekly. Home blood pressure monitors are widely available in Japan at pharmacies and electronics stores.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">4. Blood Sugar and Metabolic Panel<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why:<\/strong> Type 2 diabetes and pre-diabetes are increasingly common, particularly in men with visceral obesity. Japan has a high rate of type 2 diabetes relative to its obesity rates, partly due to genetic factors affecting insulin sensitivity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What&#8217;s tested:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fasting blood glucose:<\/strong> Normal <100 mg\/dL; pre-diabetic 100\u2013125; diabetic \u2265126<\/li>\n<li><strong>HbA1c:<\/strong> Reflects average blood sugar over 2\u20133 months. Normal <5.7%; pre-diabetic 5.7\u20136.4%; diabetic \u22656.5%<\/li>\n<li><strong>Fasting insulin:<\/strong> Helps detect insulin resistance before blood sugar rises<\/li>\n<\/ul>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Frequency:<\/strong> Annually from age 40, or more frequently if overweight or with family history of diabetes.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">5. Lipid Panel (Cholesterol)<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why:<\/strong> Dyslipidemia \u2014 abnormal cholesterol and triglyceride levels \u2014 is a primary driver of cardiovascular disease.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What&#8217;s tested:<\/strong> Total cholesterol, LDL (&#8220;bad&#8221; cholesterol), HDL (&#8220;good&#8221; cholesterol), triglycerides. Some clinics also test ApoB and Lp(a) for a more nuanced picture.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Target values:<\/strong> LDL <140 mg\/dL (lower if high-risk), HDL >40 mg\/dL, triglycerides <150 mg\/dL.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Frequency:<\/strong> Annually. Part of standard blood work in Japan&#8217;s annual health check system.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">6. Liver and Kidney Function<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why:<\/strong> Liver disease (including fatty liver, which is very common among men who drink regularly) and chronic kidney disease often develop silently.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What&#8217;s tested:<\/strong> AST, ALT, GGT, creatinine, eGFR, uric acid.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Note for Japan residents:<\/strong> Japan has high rates of hyperuricemia (elevated uric acid) among men, which increases the risk of gout and kidney stones. This is worth monitoring, especially if you consume alcohol regularly or eat a purine-rich diet.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\">7. Colorectal Cancer Screening<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why:<\/strong> Colorectal cancer is the second leading cause of cancer death in Japan. Screening reduces mortality by up to 33%.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Methods:<\/strong><\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>Fecal occult blood test (FOBT):<\/strong> Annual. Non-invasive. Standard in Japan&#8217;s municipal health screening program.<\/li>\n<li><strong>Colonoscopy:<\/strong> Recommended every 10 years starting at age 45 (or earlier with family history). Available at most major hospitals.<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\">8. Thyroid Function<\/h3>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Why:<\/strong> Thyroid disorders are often overlooked in men but can cause fatigue, weight changes, mood disturbance, and cognitive impairment \u2014 symptoms that overlap heavily with low testosterone.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>What&#8217;s tested:<\/strong> TSH, free T4, and sometimes free T3 and thyroid antibodies.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><strong>Frequency:<\/strong> Baseline at 40, then as clinically indicated.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">The Ningen Dock: Japan&#8217;s Comprehensive Health Check<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Japan offers a unique health screening system called <strong>ningen dock<\/strong> (\u4eba\u9593\u30c9\u30c3\u30af) \u2014 a comprehensive half-day or full-day health examination that covers most of the tests above, plus imaging (chest X-ray, abdominal ultrasound, and sometimes CT or MRI). Costs range from \u00a530,000 to \u00a5100,000+ depending on the facility and the extent of testing.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">For expats, several hospitals in Tokyo offer ningen dock with English-language support. Your employer&#8217;s health insurance may subsidize part of the cost. It&#8217;s an excellent way to establish a comprehensive health baseline.<\/p>\n\n\n\n<h2 class=\"wp-block-heading\">Don&#8217;t Wait for Symptoms<\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">The most dangerous health conditions after 40 are the ones that don&#8217;t announce themselves. Hypertension, pre-diabetes, early prostate changes, and low testosterone all develop quietly. By the time symptoms become obvious, you may have lost years of intervention opportunity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">An annual checkup isn&#8217;t about anxiety \u2014 it&#8217;s about information. Armed with data, you and your doctor can make informed decisions that protect your health for decades to come.<\/p>\n\n\n\n<hr class=\"wp-block-separator has-alpha-channel-opacity\"\/>\n\n\n\n<h2 class=\"wp-block-heading\">Related Articles<\/h2>\n\n\n\n<ul class=\"wp-block-list\">\n<li><a href=\"\/en\/column\/what-is-andropause\/\">What Is Andropause?
