mammograms are one of the things that suck about turning 40

Right now, over 37 million Americans—or roughly one in 10 adults—are living with diabetes. According to the Centers for Disease Control and Prevention (CDC), one in five people with diabetes do not know they have it.

The CDC recommends that all people over the age of 35 should undergo diabetes screening, which may include an A1C test, a glucose tolerance test, fasting blood sugar test, or random blood sugar test. However, if you're over 40 and haven't yet been tested, now is the time to schedule a screening.

Blood pressure testing

Over half of American adults have high blood pressure, a dangerous risk factor for stroke and heart attack. Though many doctors' offices perform blood pressure testing as part of their intake routine, you may not be tested regularly if you skip your regular checkups.

The U.S. Department of Health and Human Services says that everyone over the age of 18 should be screened for hypertension once every three to five years. However, they note that those over the age of 40 and those at increased risk of hypertension should plan on being screened annually.

Cholesterol testing


Having high cholesterol can spike your risk of cardiovascular disease. However, there are no symptoms associated with high cholesterol, meaning the only way to become aware of the problem is to be tested for it.

Though the CDC says that even children and adolescents should have their cholesterol levels checked, many people don't undergo this type of testing until later in life.

If you are over 40 and are unaware of your cholesterol levels, now is a great time to ask your doctor about screening. Healthy adults should plan on having their cholesterol tested every four to six years, though people with heart disease, diabetes, or a family history of high cholesterol should ask their doctor about being screened more frequently.

An important tool used for colon cancer screening, a colonoscopy allows your doctor to look for cancer-causing polyps or other abnormalities in the colon. While people at average risk of colon cancer can begin screenings at the age of 45, those with a family history of this cancer type should begin getting colonoscopies at 40, or 10 years before their family member's age of diagnosis.

Speak with your doctor to learn more about which medical tests may benefit you in your 40s, especially regarding any conditions of which you have a family history.
