If you’re asking about the health claim in this headline: some diabetes symptoms can become noticeable at night, but there is no single list of “9 guaranteed signs.” Nighttime symptoms may happen because blood glucose levels are too high or too low.
Possible nighttime signs that can be associated with diabetes include:
- Frequent urination at night (nocturia) — high blood sugar can cause the kidneys to remove extra glucose through urine, increasing urination.
- Excessive thirst — fluid loss from frequent urination can make you feel very thirsty.
- Night sweats — can occur with episodes of low blood sugar (hypoglycemia).
- Waking up hungry or shaky — may be related to low blood sugar during sleep.
- Poor sleep or frequent waking — glucose fluctuations can affect sleep quality.
- Dry mouth — dehydration from high blood sugar may contribute.
- Tingling, burning, or numbness in feet — nerve damage related to diabetes can cause symptoms that are more noticeable at rest.
- Unexplained fatigue in the morning — disrupted sleep or overnight glucose changes may play a role.
- Slow-healing wounds or recurrent infections — not specifically nighttime symptoms, but can be warning signs of diabetes.
These symptoms can also be caused by many other conditions. If someone has several of these signs, especially with risk factors such as being overweight, having a family history of diabetes, or experiencing increased thirst and urination, a healthcare professional can check blood glucose levels (such as fasting glucose or an HbA1c test).
