Similar to type 2 diabetes, there are usually no symptoms; however, there are warning signs for prediabetes that may mean you are at higher risk. Here are 10 warning signs of prediabetes.
- Family history. If a close family member has been diagnosed with prediabetes or type 2 diabetes, you are at higher risk. (A close family member is a parent, brother or sister.)
- Age. The older you are, the higher your risk for prediabetes. At age 40 your risk starts to rise and increases significantly after age 65.
- Race. People of African, Arab, Asian, Hispanic, Indigenous, or South Asian descent are at higher risk.
- Gestational diabetes. If a woman has had gestational diabetes (diabetes that occurs during pregnancy), she is at higher risk. As well, giving birth to a baby who weighed more than four kilograms (nine pounds) also increases a woman’s risk of prediabetes.
- Weight. Overweight or obese people have a higher risk of developing prediabetes, especially if they carry the extra weight around their abdomen. This is because the extra fat cells can cause the body to become more insulin resistant.
- Polycystic ovarian syndrome (PCOS). PCOS is a hormone imbalance that occurs in women, and can cause small, benign cysts to develop on the ovaries. Around 60-65% of women with PCOS have insulin resistance, with 70-80% of these women also being obese (BMI>30).Therefore, having PCOS increases your risk of insulin resistance, obesity, as well as prediabetes.
- Other health problems. People with hypertension (high blood pressure), high LDL cholesterol (the “bad” cholesterol), or high triglycerides (a type of fat in the blood) have a higher risk of prediabetes.
- Medications. Certain medications can increase a person’s risk of obesity, and can also increase their risk of prediabetes. These medications include:
- Corticosteroids, which are used to treat inflammatory conditions (for example, asthma, rheumatoid arthritis, psoriasis and eczema)
- Thiazide diuretics, which are used to treat high blood pressure
- Beta-blockers, which are used to treat heart failure and high blood pressure, and are sometimes prescribed after a heart attack
- Antipsychotics, which are used to treat schizophrenia, bipolar disorder and severe depression
- Statins, which are used to lower LDL cholesterol and triglyceride levels
With some medications, blood glucose levels return to normal once a person stops taking them; in other cases, the development of prediabetes and/or type 2 diabetesmay be permanent.
- Psychiatric and mental health disorders.Some psychiatric illnesses (for example, schizophrenia andbipolar disorder) have been linked toprediabetes and type 2 diabetes. Some psychiatric medications can cause people to gain a tremendous amount of weight, which can in turn lead to prediabetes. Studies have also shown that many people diagnosed with a psychotic disorder already had insulin resistance or prediabetes before they took antipsychotic medications. So, whether prediabetes is an effect of the illness, or is caused by psychiatric medications – or perhaps both of these factors – is not known at this time.
- Sleep problems. People who have obstructive sleep apnea (a condition that causes the throat muscles to relax and block the airway during sleep) have an increased risk of insulin resistance and prediabetes. As well, people who work rotating shifts or night shifts – which can cause sleep interruptions – also have an increased risk of prediabetes.
