Cannabidiol (CBD) is a natural compound that comes from the Cannabis sativa plant. It may help treat diabetes. However, using CBD products can come with risks, and CBD may not suit individuals with certain health conditions or those who are pregnant or nursing.

There is currently no cure for diabetes, but a person can control the condition with diabetes medications such as insulin, alpha-glucosidase inhibitors, and biguanides.

Some research has looked into whether or not CBD oil can also help with diabetes, though it is not currently a regulated treatment for this condition.

This article explores whether or not CBD can help with diabetes, some safety considerations, and a few products to consider.

Is CBD legal? Hemp-derived CBD products with less than 0.3% THC are legal federally but still illegal under some state laws. Cannabis-derived CBD products, on the other hand, are illegal federally but legal under some state laws. Check local legislation, especially when traveling. Also, keep in mind that the Food and Drug Administration (FDA) has not approved nonprescription CBD products, which may be inaccurately labeled.

Cannabis sativa, a plant that people may call cannabis or hemp, contains two active ingredients: delta-9-tetrahydrocannabinol (THC) and CBD.

THC contains psychoactive properties, so it may cause euphoria.

CBD, on the other hand, is non-euphoric, though it may contain small traces of THC. People using CBD will not experience the high feeling associated with cannabis use.

Types of CBD

There are three types of CBD products These are:

  • Full-spectrum CBD: This type of CBD contains naturally occurring extracts from the cannabis plant and up to 0.3% THC.
  • Broad-spectrum CBD: This type of CBD consists of naturally occurring compounds from the cannabis plant and does not contain traces of THC.
  • CBD isolate: This is the pure form of CBD, which is free of THC, plant compounds, and cannabinoids. It is odorless and has no taste.

Diabetes is a chronic condition that affects a person’s blood glucose, or sugar, regulation.

Glucose comes from the food people eat, which the body then releases into the bloodstream. When a person’s blood sugar level goes up, the pancreas releases insulin and helps glucose get into the body’s cells to promote energy.

The Centers for Disease Control and Prevention (CDC) state that when a person’s body does not produce enough insulin or their cells do not respond to insulin, they can develop diabetes. As a result, a person with diabetes may have too much sugar in their bloodstream.

According to the American Diabetes Association (ADA), having a high blood sugar level can increase the risk of other health conditions, including:

Types of diabetes

There are three types of diabetes. These are:

  • Type 1 diabetes: Type 1 diabetes develops when the body does not make insulin, and people typically receive a diagnosis of this type during childhood. The CDC state that 5–10% of people with diabetes have type 1 diabetes.
  • Type 2 diabetes: Type 2 diabetes develops when the body does not make or use insulin well. The CDC says that 90–95% of people with diabetes have type 2 diabetes.
  • Gestational diabetes: This type of diabetes can develop during pregnancy but usually resolves after the person gives birth.

The ADA claims that the Food and Drug Administration (FDA) does not regulate CBD products for diabetes.

According to the Arthritis Foundation, people with arthritis are more likely to develop diabetes than those with a healthy blood sugar level. A 2017 study looked at the effects of CBD in rats with osteoarthritis. It found that CBD reduced both inflammation and pain associated with the condition.

In another study from 2019, researchers found that a 30-day CBD treatment improved memory performance and reduced nerve inflammation in rats with chronic cerebral hypoperfusion and diabetes.

The researchers behind a 2015 study found that CBD reduced inflammation and neurotoxicity in rats with diabetes. As a result, the researchers concluded that CBD products might benefit people with diabetic retinopathy.

Possible side effects of CBD

One 2017 review states that CBD can cause:

  • fatigue
  • nausea
  • changes in appetite
  • changes in weight

Below are some of the top questions regarding using CBD for diabetes:

Does CBD oil have a direct effect on blood sugar?

No scientific studies show a direct effect of CBD on blood sugar.

Do doctors recommend CBD oil for diabetics?

Some doctors may recommend CBD oil for neuropathic pain, which may affect some people with diabetes.

However, there is currently insufficient research regarding the efficacy of CBD and how it interacts with medications to control blood glucose levels.

Is it safe to use CBD oil daily?

A 2020 systematic review investigated the safety and efficacy of different CBD dosages in adults. The study concluded that there were insufficient data regarding the safety of CBD. However, the authors noted that most studies reported no adverse events following acute administration of CBD and mild to moderate effects following chronic administration of CBD.

Anyone considering taking CBD for their diabetes should consult their doctor to determine dosages and frequency of administration.

Diabetes is a condition that develops when a person has a high sugar level in their bloodstream.

Although there is currently no cure for diabetes, a person can control and treat diabetes with medications to alleviate the symptoms and manage their blood sugar level.

Some evidence suggests that CBD products may help people with diabetes control their condition.

People who are pregnant, nursing, or taking prescription medications should seek medical advice before using any CBD products.
