How the body typically changes
- Bones are usually at their thickest and strongest in early adult life. From around age 35, everyone gradually starts to lose bone, and after menopause falling oestrogen levels can make bone density drop quickly. Source
- The prostate starts a second phase of growth around age 25 and keeps growing through life. Non-cancerous enlargement (benign prostatic hyperplasia) is the most common prostate problem after age 50, and it rarely causes symptoms before age 40. Source
- Hearing tends to decline with age: among adults aged 20 to 69 in the United States, age is the strongest predictor of hearing loss, and hearing loss is greatest at ages 60 to 69. (United States) Source
Main health risks
- Worldwide, most road traffic deaths are among people of working age, from 18 to 59. Source
- Worldwide, people aged 20 to 39 are disproportionately harmed by alcohol, with the highest proportion of deaths caused by alcohol of any age group. No form of drinking is risk-free. Source
- Testicular cancer is most common between ages 15 and 49, and it can affect anyone who has testicles. Source
- Worldwide, about 33% of adults aged 30 to 79 have high blood pressure (hypertension). Most people with it feel no symptoms, and about 44% of those affected do not know they have it. Source
- Type 2 diabetes can develop at any age, but it becomes more likely from age 35. Overweight or obesity and a family history of diabetes also raise the risk, while keeping a healthy weight and being physically active may help avoid some risk factors. Source

Everyday health
- Guidelines for adults aged 19 to 64 advise at least 150 minutes of moderate-intensity or 75 minutes of vigorous-intensity activity a week, muscle-strengthening activities on at least 2 days a week, and breaking up long periods of sitting. Source
- Adults aged 18 to 60 need 7 or more hours of sleep each day, and adults aged 61 to 64 need 7 to 9 hours. Source
- UK guidelines for people over 18 advise not regularly drinking more than 14 units of alcohol a week and, for those who drink that much, spreading it over 3 or more days. Staying within this keeps risks low but does not make drinking safe. (England, UK) Source
- WHO guidance is for everyone older than 10 to aim for at least 400 grams of fruit and vegetables and at least 25 grams of naturally occurring fibre a day, and for adults to keep salt below 5 grams a day. Source
- In the United States, tobacco use is the leading cause of preventable disease and death. E-cigarette use is most common among adults aged 18 to 24, and cigarette smoking among adults aged 45 to 64. (United States) Source
If your ancestry or background is…
South Asian · Chinese · Other Asian · Middle Eastern · Black African or African Caribbean
NICE (UK) guidance says people with a South Asian, Chinese, other Asian, Middle Eastern, Black African or African-Caribbean background tend to carry more fat around the abdomen and face weight-related risks at a lower BMI. For adults it uses lower thresholds: overweight from 23 to 27.4, obesity from 27.5 or above.
National Institute for Health and Care Excellence (NICE) · England, UK · Source
Asian American
USPSTF (US) guidance, which recommends screening adults aged 35 to 70 who have overweight or obesity for prediabetes and type 2 diabetes, says a lower BMI cut point of 23 or more may be appropriate for Asian American people, because differences in body fat composition mean the usual BMI thresholds underestimate their risk.
US Preventive Services Task Force · Source
Fair skin types
USPSTF (US) guidance says people with fair skin types (pale skin, light hair and eye colour, freckles, or skin that sunburns easily) are at higher risk of skin cancer. It recommends counselling people aged 6 months to 24 years, and parents of young children, about limiting exposure to ultraviolet (UV) radiation, and selectively offering this counselling to adults older than 24.
US Preventive Services Task Force · Source
Born in, or with parents from, a region where hepatitis B is more common
CDC (US) guidelines list people born in regions where hepatitis B infection prevalence is 2% or more among those at increased risk, and recommend testing them, regardless of age, if they may have been susceptible to infection. The same applies to people born in the United States who were not vaccinated as infants and whose parents were born in regions where prevalence is 8% or more.
Centers for Disease Control and Prevention (US) · Source
East Asian
The MHLW (Japan) drinking guideline, mainly for adults aged 20 and over, says that in East Asia a number of people have a weak enzyme for breaking down alcohol and may flush red when they drink; about 41% of people in Japan are thought to react this way. It warns that long-term drinking greatly raises their risk of mouth and oesophageal cancer, even once it stops feeling unpleasant.

When to see a doctor
- Sudden weakness or drooping on one side of the face, weakness or numbness in one arm, or slurred or confused speech can be signs of a stroke, which is an emergency: call your local emergency number straight away, even if the symptoms stop after a short time. A stroke can happen at any age. Source
- Chest pain that feels crushing or squeezing, possibly spreading to the arm, neck or jaw, along with shortness of breath, feeling sick or sweating, can be signs of a heart attack, which needs emergency treatment: call your local emergency number straight away. Source
- A lump or swelling in the testicles, a change in their shape or feel, or aching that does not go away is a reason to see a GP; most lumps are not serious. Sudden, severe testicle pain needs emergency care. Contact a doctor or your local health service; in an emergency, call your local emergency number. Source
- Very high blood pressure (usually 180/120 or higher) can cause severe headache, chest pain, dizziness, difficulty breathing, blurred vision or confusion; these symptoms together with high blood pressure need care straight away. Contact a doctor or your local health service; in an emergency, call your local emergency number. Source
If you are worried about a symptom, contact a doctor or your local health service. In an emergency, call the emergency number for your country.
