Several Possible Causes of Why Do You Feel Dizzy After Eating Sugar?

You may be wondering, Why do I feel dizzy after eating sugar ? There are several possible causes of postprandial hypotension. It could also be a symptom of a worse condition. For example, prediabetes or high blood pressure are causes of this condition. Other reasons may include food sensitivities, stomach surgery, or an enzyme deficiency. A doctor can help you determine the cause of your dizziness. But for the most part, it’s easy to understand why you feel dizzy after eating sugar.

Limiting your intake of sugar and processed foods 

It is crucial to monitor your blood pressure regularly, especially if it is accompanied by other symptoms like dizziness or other obvious signs. It is also a good idea to monitor your blood pressure at home using a blood pressure cuff that you can purchase over the counter. Keeping track of your pressure can help you make the necessary changes in your diet. Ultimately, limiting your intake of sugar and processed foods can help you control your blood pressure.


If you’ve ever felt dizzy after eating sugar, it can be caused by several factors. For instance, simple carbohydrates are processed faster than complex ones, requiring more blood flow to digest them. However, complex carbohydrates and proteins take longer to absorb into the body, resulting in a slower onset of dizziness. While there have been several attempts to treat postprandial hypotension, such treatments have not been proven effective in clinical trials. Depending on the cause of your dizziness, you may need to undergo physical therapy or consider changing your diet.

Medications that cause dizziness

Diabetics often take medications to treat various medical conditions, such as high blood sugar. Some of these medications affect potassium levels, which can cause dizziness. People with diabetes may also be taking antibiotics or water-retention medication. These medications may also cause dizziness. Besides insulin and blood pressure medications, other drugs may also cause dizziness. Other drugs that may trigger these symptoms include anti-inflammatories, steroidal anti-inflammatory drugs, and antibiotics. Depending on the specific case, doctors may recommend additional tests and treatments. In some cases, underlying medical conditions, such as heart problems, low thyroid levels, or nutritional deficiencies, may cause the symptoms of diabetes.

Postprandial hypotension

Although there is no single cause of postprandial hypotension, a diet high in carbohydrates or high-fat foods can lead to the condition. Eating smaller, more frequent meals is an excellent way to avoid the onset of this condition. If your blood pressure falls below average in the first two hours after eating, you may have postprandial hypotension. The Harvard Health website recommends eating smaller lunches and drinking plenty of water. Foods that digest slowly include whole grains, beans, lean protein, and healthy oils.

Certain medical conditions can increase the risk of postprandial hypotension. Diabetes and Parkinson’s disease interfere with the autonomic nervous system. People who take antihypertensive medications can experience significant drops in blood pressure after eating. Sometimes these medications are too effective, causing the blood pressure to return to normal levels. But if you’re at risk for postprandial hypotension, make sure you talk to your doctor immediately.


Hypoglycemia happens when the blood sugar levels in the body drop suddenly. It can occur due to various causes, including an insulin injection or diabetes medication. Whether it’s a sugar crash or a dehydration complication, dizziness may occur. Hypoglycemia can affect the brain in several ways, and some medications can cause the symptoms. To know for sure, consult your doctor and ask for a complete list of side effects.

Reactive hypoglycemia occurs when blood glucose levels decrease quickly after a meal. People with diabetes and prediabetes may experience these symptoms. Other factors that can cause blood glucose levels to fall after eating include stomach surgery, which can make it difficult for the body to absorb glucose from food. Rare deficiencies in digestive enzymes can also cause blood glucose levels to drop rapidly. Diagnosis and treatment of the condition are important because of the lifestyle implications.

Reactive (or postprandial) hypoglycemia

Reactive hypoglycemia is a severe condition that makes a person feel lightheaded and dizzy after eating a large amount of sugar. You can treat it through diet and lifestyle changes. The best way to treat it is to eat a balanced diet that comprises complex carbohydrates and plenty of fruit. In addition, you should avoid simple carbs and sugar, which are broken down into glucose.

A suitable reactive hypoglycemia treatment plan should focus on your blood glucose level control. Eat small meals often, and aim to eat every two to three hours. You may have to eat smaller meals more frequently, but ensure that you eat when you feel hungry. It is also essential to eat a balanced breakfast. Eating breakfast is an excellent way to set the stage for a successful day.


The symptoms of diabetes are varied and often include dizziness. People with type 2 diabetes experience symptoms such as fatigue, nausea, and vision changes. People with type 1 diabetes, however, experience none of these symptoms. Diabetic ketoacidosis is a serious condition that can lead to blindness and death. In some cases, treatment can be as simple as dietary changes. However, if you have this condition, a doctor may prescribe glucose-containing medication.

Low blood pressure

It is crucial to monitor your blood pressure regularly to determine the exact cause of your low reading. High blood pressure can lead to cardiovascular problems such as heart attack and stroke. If the cause of your low reading isn’t clear, you should consult a physician. Low blood pressure is more dangerous than you may think. It can result in fainting and loss of consciousness, and can even be life-threatening. Your doctor can help you take proper treatment to restore your health and keep your blood pressure in the normal range.
