Detox When You Have Diabetes or High Blood Pressure: Why It Changes the Plan

Detox is one of the first steps in addiction treatment. It involves withdrawing from substances while under medical supervision, and it’s one of the hardest and most vulnerable stages of recovery. For many people, however, moving through detox gives them confirmation of their strength and hope that they can — and will — recover.

Every detox experience should be tailored to the individual person. The fragile nature of detox and the high risk of relapse means each person’s addiction and medical history should be integrated into their care, as well as their specific treatment goals. If a person has diabetes or high blood pressure, those conditions absolutely must inform their detox journey.

A person with diabetes or high blood pressure can participate in detox, but they require additional considerations to stay safe and to have a higher chance of finishing the program. Let’s take a closer look, drawing on my time working at a physician-led medical detox center.

Risks Associated with Diabetes or High Blood Pressure During Detox

In the U.S., more than 40 million people (about 12% of the population) have diabetes. A further 11.0 million people are estimated to be undiagnosed with diabetes [1]. Meanwhile, close to half of the total population has high blood pressure [2]. That means many people who come to detox have diabetes, high blood pressure, or both.

It’s important that anyone with diabetes or high blood pressure let their detox care team know about the condition(s) at intake. The earlier the team is aware, the sooner they can make accommodations to keep the person safe and to ensure that the person finishes the program and has the greatest chance of moving through other levels of care toward long-term recovery. 

Some of the risks that arise in detox when a person has diabetes or high blood pressure are:

Diabetic Risks

Unstable blood glucose levels. Changes in eating habits plus stress responses during detox can mean blood sugar levels fluctuate and are harder to manage. Alcohol can cause low blood sugar, sometimes delayed or overnight, especially in people who take insulin or sulfonylureas. Stimulants can push blood sugar too high and raise the risk of ketoacidosis [3]. 

Medication interactions. Some medications used in detox may affect blood glucose levels, which requires the care team to be extra attentive to medication choices and dose changes. 

Overlapping blood sugar problems and withdrawal symptoms. Sweating, shaking, confusion, anxiety, and changes in energy levels are signs of both hypoglycemia (low blood sugar) and withdrawal from addictive substances.

Health complications. Dehydration and poor electrolyte balance, as well as the risk of infection among intravenous substance users, can create health complications among people with diabetes.

Diabetic-specific considerations. Diabetic ketoacidosis (DKA) or hyperosmolar hyperglycemic state (HHS) are life-threatening episodes that can occur in people with diabetes. Detox teams have to be aware and prepared for these possible events.

High Blood Pressure Risks

Stress. High levels of discomfort and stress, including vomiting and cravings, can exacerbate already high blood pressure. 

Risk of Delirium Tremens (DTs). In severe alcohol withdrawal, DTs is a potentially fatal withdrawal symptom. High blood pressure has been associated with a higher risk of developing DTs [4]. 

Substance influence on blood pressure. Methamphetamine and other stimulants, such as cocaine, can raise blood pressure. Detox teams need to assess the person’s baseline blood pressure and any cardiovascular risks before creating a course of care. 

Medication interactions. If the person is taking medications, such as antihypertensives, these may interact with medications given during detox. Detox medications may also affect blood pressure even if no other medications are present.

Hospitalization. People with poorly controlled blood pressure or significant heart disease may need detox in a hospital, where closer monitoring is available [5].

While these risks can apply to anyone with diabetes or high blood pressure while in detox, there are many variables that impact the likelihood and severity of the risks. The type of addiction being treated, the frequency and intensity of substance use, and co-occurring physical and mental health conditions all play a role. 

How Detox Teams Should Tailor Care

Individualized care for substance use disorders can help improve the quality of care, retention rates within detox programs, engagement with treatment, and lower risk of relapse. Among people with diabetes or high blood pressure, individualized care is even more essential because it helps provide additional resources for the conditions, ensures extra monitoring around the conditions, prevents dangerous medication interactions, and gives people the highest chance of successfully withdrawing from substances. 

Accommodating diabetes and high blood pressure starts at intake for detox. Teams should ask people about their medical history, including if they have diabetes and high blood pressure, or if the conditions run in their family. They should also ask about the medications people are taking, any complications they’ve experienced, recent blood tests (if they have them), and strategies that have helped them manage their condition. It’s worth noting that many people with an SUD and diabetes do not receive high-quality care for diabetes [6]. 

Intake is also when detox teams should look for possible interactions between diabetes or blood pressure medications and detox medications. If they find a risk, the team should adjust the detox medications or doses, working with other specialists when needed [4]. Medications should be clearly scheduled so patients don’t miss doses during detox. 

Once treatment begins, care teams have to closely monitor blood glucose and blood pressure levels among people with diabetes or high blood pressure. Because of the likelihood of reduced appetite and vomiting during detox, they should also ensure people have snacks and stay hydrated (as well as have regular, nutritious meals) to lower the risk of hypoglycemia. 

During detox, care teams have to be able to distinguish symptoms that can be a result of substance withdrawal or diabetes or high blood pressure. Sweating, shaking, anxiety, and confusion are all overlapping symptoms, and teams need to assess when they are part of withdrawal or when they represent a preexisting health issue. Every detox center should have protocols around diabetic and blood pressure emergencies, including when a hospital transfer is necessary.

Tailored Care Means Safer, More Impactful Detox

Individualized detox should be the baseline for any person seeking help to withdraw from addictive substances. Tailored care not only makes treatment more impactful, but in the case of diabetes or high blood pressure, it prioritizes people’s safety.

By taking steps to shape care around conditions such as diabetes and high blood pressure, detox teams show people from day one that they are experts, empathetic, and effective in their work.
