Benign prostatic hyperplasia, or an enlarged prostate, is the single most common disorder in aging men. About 50% of men between ages 51 and 60 have it, rising to 70% in their 60s and roughly 80% after age 70. But the prostate is far from the only concern. Cardiovascular disease, muscle loss, erectile dysfunction, declining testosterone, diabetes, and depression all become significantly more likely as men age, and several of these conditions feed into one another.
Enlarged Prostate Affects Most Older Men
The prostate gland naturally grows throughout a man’s life. By middle age, this growth can start squeezing the urethra, making it harder to urinate. The condition, called benign prostatic hyperplasia (BPH), is not cancer and doesn’t increase cancer risk, but it causes symptoms that progressively worsen: a weak urine stream, frequent nighttime trips to the bathroom, difficulty starting urination, and a feeling that the bladder never fully empties.
Because BPH affects the vast majority of men who live long enough, it’s often treated as an inevitable part of aging rather than a disease. Mild cases typically need nothing more than monitoring. When symptoms interfere with sleep or daily life, medications can relax the muscles around the prostate or slowly shrink the gland itself. For more severe cases, minimally invasive procedures can open the blocked urethra. The key distinction to understand: BPH is a quality-of-life issue, not a life-threatening one, but ignoring it can lead to urinary tract infections or bladder damage over time.
Heart Disease and High Blood Pressure
Cardiovascular disease is the leading killer of men in every older age group, and the numbers are striking. According to American Heart Association data from 2017 to 2020, 77.8% of men ages 60 to 79 had some form of cardiovascular disease (including high blood pressure), climbing to 85.9% in men over 80. Coronary heart disease specifically affected 22.4% of men ages 60 to 79 and 30.6% of men over 80.
High blood pressure is the main driver. About 72% of men ages 65 to 74 have it, and that rises above 80% after age 75. Years of elevated pressure damages artery walls, stiffens the heart muscle, and raises the risk of heart attack and stroke. Heart failure, where the heart can no longer pump efficiently, affects roughly 7.5% of men in their 60s and 70s. What makes cardiovascular disease especially dangerous in older men is that it often develops silently. Blood pressure can be high for years without obvious symptoms, which is why annual blood pressure checks remain one of the most important screening habits after 65.
Testosterone Decline and Its Effects
Testosterone levels drop about 1% per year starting in a man’s late 30s. By the time a man reaches his 60s or 70s, levels may have fallen enough to cause noticeable changes: reduced energy, lower sex drive, loss of muscle mass, increased body fat, and mood changes like irritability or low motivation. When levels fall below 300 nanograms per deciliter and symptoms are present, the condition is called late-onset hypogonadism.
Not every man with low numbers on a blood test needs treatment. The diagnosis requires both low levels and symptoms that affect daily life. Men with type 2 diabetes or obesity are significantly more likely to develop clinically low testosterone, creating a cycle where low hormones make it harder to maintain a healthy weight, and excess weight further suppresses hormone production.
Erectile Dysfunction
Erectile dysfunction becomes dramatically more common with age. Survey data from the National Health and Nutrition Examination Survey show that about 8% of men in their 40s report ED, compared to 77.5% of men aged 75 and older. Those numbers reflect the reality that ED is rarely a standalone problem. It’s closely tied to cardiovascular health, diabetes, and testosterone levels, all of which deteriorate with age.
ED is also one of the earliest warning signs of heart disease. The blood vessels supplying the penis are smaller than those feeding the heart, so they tend to show damage from high blood pressure, high cholesterol, or diabetes sooner. A man who develops ED without an obvious cause should consider it a prompt to check his cardiovascular health, not just a sexual concern.
Muscle Loss and Sarcopenia
After age 50, men lose 1 to 2% of their leg muscle mass per year and 1.5 to 5% of their strength per year. When this loss becomes severe enough to impair physical function, it’s called sarcopenia. The condition is diagnosed in stages: probable sarcopenia is identified when grip strength falls below 27 kilograms or it takes longer than 15 seconds to stand up from a chair five times. Confirmed sarcopenia adds measurably low muscle mass, and severe sarcopenia means both low mass and poor physical performance, like walking slower than about 1.8 miles per hour.
Sarcopenia matters because it predicts falls, fractures, loss of independence, and earlier death. Unlike some conditions on this list, it responds well to intervention. Resistance exercise is the most effective treatment at any age, and adequate protein intake (higher than what younger adults need) helps preserve muscle. The problem is that most men don’t recognize gradual strength loss until it’s already advanced, because daily routines adjust to accommodate declining ability.
Type 2 Diabetes
Nearly 29% of adults aged 65 and older have diabetes, and men carry a higher overall burden, with a total diabetes prevalence (diagnosed and undiagnosed combined) of about 14.9%. The risk climbs with age because of several converging factors: declining muscle mass reduces the body’s ability to absorb blood sugar, physical activity tends to drop, and body fat, especially around the abdomen, increases insulin resistance.
Undiagnosed diabetes is a particular concern in older men. The classic symptoms of frequent urination and thirst can be masked by BPH or simply attributed to aging. Screening every three years is recommended for men over 65 who are overweight. Left unmanaged, diabetes accelerates every other condition on this list: it worsens heart disease, speeds muscle loss, drives erectile dysfunction, and doubles the risk of low testosterone.
Bone Loss and Hip Fracture Risk
Osteoporosis is often thought of as a women’s health issue, but men account for a significant share of hip fractures, and they fare worse when they break a bone. One-year mortality after a hip fracture ranges from 17 to 25%, with affected individuals facing three to four times the risk of death compared to peers of the same age. Men have historically had higher hip fracture mortality rates than women, though that gap has been narrowing. Between 1999 and 2023, the age-adjusted hip fracture mortality rate in men dropped 43%, from about 40 to 23 per 100,000.
Bone density screening isn’t routinely recommended for all men the way it is for women, so osteoporosis in men often goes undetected until a fracture occurs. Risk factors include low testosterone, long-term steroid use, smoking, excessive alcohol, and low body weight.
Depression in Older Men
Depression is underdiagnosed in older men. While women screen positive for depression at roughly twice the rate of men, the suicide rate in older men with depression is at least six times higher than in women of the same age. This gap suggests that many depressed older men are never identified or treated.
Part of the problem is presentation. Older men with depression are less likely to report sadness and more likely to show irritability, social withdrawal, fatigue, or physical complaints like unexplained pain. Research from a large Chilean study found that only about 19% of men who screened positive for depression had actually received a diagnosis, compared to 34% of women. Men with more education were more likely to be diagnosed, suggesting that awareness and willingness to engage with healthcare play a significant role in whether depression gets caught.
Cognitive Decline
Mild cognitive impairment, a stage between normal age-related forgetfulness and dementia, is common in older adults and progresses to dementia at varying rates depending on the setting. In community-based populations, about 3% of people with mild cognitive impairment convert to dementia each year. In clinical settings, where patients have already sought help for memory concerns, that rate climbs to 10 to 15% per year.
The practical difference matters. A man who notices occasional word-finding difficulty or needs more time to learn new information is experiencing something that may never progress. A man whose family notices consistent memory lapses, trouble following conversations, or difficulty managing finances is showing signs that warrant evaluation. Cardiovascular health, physical activity, social engagement, and diabetes management all influence how quickly cognitive decline progresses, which ties this condition back to nearly every other item on this list.
Screening Schedule After 65
Staying ahead of these conditions depends on consistent screening. For men 65 and older, the key recommendations include:
- Blood pressure: checked at least once a year
- Cholesterol: every four to six years, or more often with known risk factors
- Colorectal cancer: regular screening until age 75, typically colonoscopy every 10 years (ages 76 to 85 should discuss continuing with their provider)
- Diabetes: every three years if overweight, up to age 70
- Abdominal aortic aneurysm: one-time ultrasound for men ages 65 to 75 who have ever smoked
- Eye exam: every one to two years starting at 65
- Prostate cancer (PSA test): an individual decision before age 70, generally not recommended after 70
The interconnected nature of these conditions means that managing one often improves several others. Controlling blood pressure protects the heart, kidneys, and brain. Maintaining muscle through exercise improves blood sugar, supports bone density, and reduces fall risk. Treating low testosterone can improve energy, mood, and sexual function. For aging men, the most effective health strategy isn’t targeting any single disorder but recognizing how deeply they’re all linked.
