When an individual has diabetes, some symptoms can affect their overall health. These can come from the condition itself, other health issues, and the side effects of certain medications. Show Dizziness is one symptom that diabetics may experience. This can be due to low blood sugar, high blood sugar, low blood pressure, retinopathy, vestibular disorder, medication side effects, or dehydration. Verywell / Laura Porter Why Diabetics May Experience DizzinessThere are many reasons why diabetics may experience dizziness, including:
Hypoglycemia (Low Blood Sugar)Hypoglycemia occurs when an individual has a very low level of blood sugar. The brain depends on blood sugar to function properly and as an energy source. The hormones that the brain depends on to raise blood sugar levels are norepinephrine and epinephrine. When the brain doesn’t get enough of these hormones it can’t function properly. This can lead to:
Hypoglycemia is common among diabetic patients. This can be caused by:
HyperglycemiaHyperglycemia is high blood glucose. This happens when the body has too much sugar in the blood and there is not enough insulin to distribute the proper amount of glucose that is needed in the blood. Many diabetics are hyperglycemic. It occurs when:
Hyperglycemia can cause many issues if not treated. Complications may include:
Verywell HypertensionIf a person has hypertension—high blood pressure—it can lead to heart disease, stroke, and other complications. If an individual has diabetes, they are twice as likely to get high blood pressure. In addition, individuals with diabetes are four times as likely to develop heart disease than someone who doesn’t have diabetes. Approximately two-thirds of adults who have diabetes also have increased blood pressure and/or use prescription medication for hypertension. Some symptoms of high blood pressure include:
This, along with diabetic symptoms, can cause complications. Verywell DehydrationThere are times when diabetics have excessive thirst. This is due to excess glucose, and the kidneys being overworked to absorb and filter that glucose. If the kidneys can’t do this effectively, the extra glucose will come out through the urine. This will also pull fluids from other tissues causing dehydration. In turn, drinking more water causes more urination. Dehydration Symptoms MedicationsThere are different medications that diabetics take. Some patients have other conditions, and the medication that they take can be for a number of reasons. If a diabetic patient is on medication for blood pressure or water retention, this can drop both the blood pressure and potassium levels, causing dizziness. Other medications such as antibiotics, anti-inflammatories, and nonsteroidals can cause dizziness. Vestibular DysfunctionVertigo and dizziness are known symptoms of vestibular balance disorder. This condition is more common as people age. Individuals who have diabetes have an increased risk of vestibular dysfunction. The condition was found in 53.6% of individuals with diabetes versus 33.2% of individuals who don’t have diabetes. In addition, the individuals with diabetes had:
This condition is usually diagnosed by an ear, nose, and throat doctor (ENT). It is important to speak with your healthcare professional to understand the condition and get proper treatment. Treatment and PreventionTo manage diabetes, it is important to work closely with your healthcare provider. Eat healthy, exercise as recommended, and take your prescribed medication. Also be aware that several conditions that can cause dizziness are related to diabetes. Monitoring blood sugar, diet, and food consumption are helpful factors. Continued conversations with your healthcare provider will help you manage your health the best way possible. A Word From VerywellDizziness can be a scary experience. If you do experience dizziness, don’t panic. The best thing to do is to try to get into a safe position to avoid falling. From there you can call someone to help you if you feel that you need assistance. If the dizziness is excessive and continuous, avoid driving, using machinery, bending, or moving around too much. It is important to speak with your healthcare provider regarding the dizziness so they can help you determine the root cause and get the proper treatment for prevention. What does it mean when diabetics feel dizzy?Anyone with type 2 diabetes who experiences frequent or severe dizziness should discuss this symptom with a doctor. Dizziness could be a sign of uncontrolled blood sugar or dehydration, both of which can cause severe complications without treatment.
Can high sugar make you dizzy?High blood sugar levels (hyperglycemia) can cause polyuria, which in turn can lead to dehydration by passing too much fluid out of the body in an attempt to remove excess glucose. With low levels of water in the body, the brain may struggle to function correctly and cause light headedness.
