Laxatives and blood sugar spikes

Laxatives are often used to treat constipation, a common complication in people with diabetes. However, it is important to understand the potential impact of laxatives on blood sugar levels, especially for individuals with diabetes. Some laxatives may cause a spike in blood sugar levels, which can be dangerous for people with diabetes. Therefore, it is crucial to select the appropriate type of laxative and use them under medical supervision.

The Link Between Diabetes and Constipation

Diabetes is a condition characterised by high blood sugar levels, which can lead to nerve damage, known as diabetic neuropathy. This nerve damage can affect the digestive tract, resulting in constipation, diarrhoea, or incontinence. Research suggests that people with diabetes have a higher risk of developing constipation, with up to 60% of people with long-standing diabetes experiencing this issue.

The Effect of Laxatives on Blood Sugar

Laxatives can have varying effects on blood sugar levels. Some types of laxatives, such as stimulant laxatives and stool softeners, may not be suitable for long-term use and can cause spikes in blood sugar levels. This is particularly relevant for people with diabetes, as they need to carefully manage their blood sugar levels to prevent further complications. Therefore, it is essential to consult a doctor before using laxatives, especially for those with diabetes.

Safe Options for Constipation Relief

There are alternative treatment options for constipation that may be safer for individuals with diabetes. These include:

  • Increasing fibre intake by consuming whole grains, fruits, and vegetables.
  • Staying hydrated by drinking plenty of water.
  • Engaging in regular physical activity to stimulate the digestive system.
  • Using bulk-forming laxatives, which are generally considered safe for people with diabetes.

Medical Advice

It is important to consult a doctor or healthcare provider before taking any laxatives, especially for individuals with diabetes. They can recommend the most suitable treatment option and provide guidance on dosage and potential side effects. Additionally, they can advise on any necessary lifestyle changes, such as diet and exercise modifications, to help manage both diabetes and constipation effectively.

Diabetes and constipation

Constipation is a common complication in people with diabetes. An older study found that around 60% of people with long-standing diabetes experience constipation. This is due to the damage that high blood sugar levels can inflict on the nerves controlling the digestive tract, leading to diabetic neuropathy, or nerve damage. This can cause constipation, diarrhea, and incontinence.

Causes of Constipation in Diabetics

Nerve Damage

High blood sugar levels from type 1 and type 2 diabetes can lead to nerve damage, which may affect the nerves controlling the digestive tract. This can slow down the movement of food through the intestines, leading to constipation. Nerve damage can also cause gastroparesis, or delayed gastric emptying, which can lead to unstable blood sugar levels.

Medication

People with diabetes may take medications that can slow gut mobility and cause constipation. It is important to discuss the side effects of any medications with a doctor.

Diet

A poor diet can also cause constipation in people with diabetes. A diet low in fiber and high in sugar-free sweeteners, for example, can lead to digestive issues. It is important for people with diabetes to eat a well-balanced diet with plenty of fiber to prevent constipation.

Treating Constipation in Diabetics

Natural Solutions

Simple solutions such as increasing fiber intake, drinking more water, and getting regular physical activity can help to regulate digestion and treat constipation.

Laxatives

Laxatives may provide relief from constipation, but they should be used carefully and only under the guidance of a doctor. Some laxatives are not intended for long-term use and may cause a spike in blood sugar levels. Bulk-forming laxatives are generally considered safe for most people.

Blood Sugar Management

Proper blood sugar management is often the best solution for regulating digestion and preventing constipation in people with diabetes. It can prevent nerve damage and improve overall gut health.

Diabetic neuropathy

There are four main types of diabetic neuropathy: peripheral, autonomic, proximal, and focal. Peripheral neuropathy is the most common type, affecting the feet and legs, and sometimes the hands and arms. It can cause numbness, tingling, burning, and pain in the affected areas. Autonomic neuropathy affects the nerves that control internal organs, leading to issues with heart rate, blood pressure, digestion, sexual function, and more. Proximal neuropathy is a rare and disabling type that affects the hip, buttock, or thigh, causing severe pain and muscle weakness. Focal neuropathy involves damage to a single nerve, most often in the hand, head, torso, or leg, and can lead to paralysis or muscle weakness.

The risk of developing diabetic neuropathy increases with poor blood sugar control, a longer duration of diabetes, kidney disease, being overweight, and smoking. However, it can often be prevented or slowed down with consistent blood sugar management and a healthy lifestyle. Maintaining a healthy gut and preventing constipation are also important for people with diabetes, as constipation can be a common complication. While laxatives may provide relief, they should be used carefully and only after consulting a doctor, as some laxatives may cause a spike in blood sugar levels.

Diet and exercise

Diet

  • Eat a balanced diet: Eating a well-balanced diet is essential for preventing blood sugar spikes and maintaining a healthy weight. Include a variety of fibre-rich foods, such as fruits, vegetables, whole grains, and legumes.
  • Understand the glycemic index (GI): The glycemic index measures how quickly a food can raise your blood sugar levels. Opt for low-GI foods like dried beans, legumes, and non-starchy vegetables. If you do eat high-GI foods, balance them with low-GI options.
  • Count your carbohydrates: Keep track of the total carbohydrates you consume at each meal, especially if you take insulin. This will help you adjust your insulin dose accordingly.
  • Increase your fibre intake: Aim for 25-30 grams of fibre per day, but increase your intake gradually. Fibre helps regulate blood sugar and can be found in foods like oatmeal.
  • Stay hydrated: Drink plenty of water throughout the day. Avoid sugary drinks, and opt for water or unsweetened tea instead.
  • Snack smart: Choose healthy snacks like carrots or grapes instead of packaged foods, which are often high in calories, salt, and added sugar.
  • Measure your meals: Keep an eye on your portion sizes to manage your blood sugar. Use measuring cups and scales to portion out your food.

Exercise

  • Get moving: Physical activity stimulates the colon and encourages healthy bowel habits. Aim for at least 30 minutes of moderate-intensity exercise, 5 days a week. Even a 5-minute walk is a good start.
  • Try different types of exercise: All forms of exercise, including aerobic and resistance training, are beneficial for lowering blood glucose levels. Find an activity you enjoy, such as walking, dancing, swimming, or biking.
  • Exercise at the right time: Try working out at different times of day to find the schedule that helps stabilise your blood sugar levels. Generally, exercising 1-3 hours after eating is recommended, as blood sugar levels tend to be higher during this time.
  • Be cautious: Always carry glucose tablets or an emergency snack, especially if you take insulin. Check your blood sugar levels before and after exercising to ensure they remain stable.

Medication

Certain medications can cause constipation, including some drugs prescribed to people with diabetes. These include opioids for peripheral neuropathy, anticholinergics for bladder control, and calcium channel blockers to lower blood pressure. GLP-1 receptor agonists and metformin, which are used to manage blood sugar in people with diabetes, can also cause constipation.

If you suspect that a medication is causing constipation, consult a doctor before stopping or changing your prescription. Doctors may be able to suggest alternative treatments or dosages.

Laxatives can be used to treat constipation, but some may cause a spike in blood sugar and are not intended for long-term use. It is important to consult a doctor about which types of laxatives are safe to use and whether they may interfere with other medications.
