Don’t Try This at Home – the need for medication supervision

There are some things that people should not do on their own and one of them is to begin a low carb or ketogenic diet without first consulting with their doctor, especially if they take certain types of medication. Medical supervision is absolutely required before a person changes the level of  their carbohydrate intake if they are taking;

(1) insulin

(2) medication to lower blood glucose such as sodium glucose co-transporter 2 (SGLT2) medication including Invokana, Forxiga, Xigduo, Jardiance, etc. and other types of glucose lowering medication such as Victoza, etc.

(3) medication for blood pressure such as Ramipril, Lasix (furosemide), Lisinopril / ACE inhibitors, Atenolol / β-receptor antagonists

(4) mental health medication such as antidepressants, medication for anxiety disorder, and mood stabilizers for bipolar disorder and schizophrenia.

I don’t provide low carbohydrate dietary services those taking insulin (either Type 1 Diabetes or Type 2 Diabetes), but encourage those considering adopting this type of lifestyle to first consult with a healthcare professional with CDE certification, as well as their family doctor. This is very important because clinical studies indicate that insulin levels need to be adjusted downward very soon after beginning a low carbohydrate or ketogenic diet and this must be medically supervised.

I also recommend to those taking medication for mental health conditions that they consult with their psychiatrist and/or family practice physician before changing their diet. A low carb or ketogenic diet may have an effect on the dosage of medication required, especially with mood stabilizing medications such as Lithium. (A recent article written by Psychiatrist Georgia Ede, MD related to a ketogenic diet appeared in Psychology Today and appears here.)

Why do I advise people coming to me to implement a low carbohydrate or ketogenic lifestyle and taking medication to control their blood sugar or blood pressure first consult with their doctor before changing how they eat? It is because eating less carbohydrate can result in blood sugar levels and blood pressure coming down fairly soon afterward and this can have serious consequences if dosages of these medications are not monitored and adjusted downward (and often being discontinued entirely).  For example, a sudden drop in blood pressure could result in people becoming dizzy or confused and could even result in injury to themselves or others if they ‘blacked out’ while walking or driving a car.

Some medications which lower blood sugar such as sodium glucose co-transporter 2 (SGLT2) medication including Invokana, Forxiga, Xigduo, Jardiance, etc. can result in life-threatening and even fatal cases of a very serious condition called “Diabetic ketoacidosis (DKA)” even with no change in diet, but these risks can be increased for patients on a very low carbohydrate diet as the combination of the medication and the low carb diet may increase the amount of ketone production (see Health Canada’s Safety Review here).

Those with significant alcohol consumption who are taking these medications are at risk for DKA, so it is very important that if you drink alcohol on a regular basis and take these medications to tell your doctor. If you are taking any of these medications and come to me, I will ask you about your alcohol consumption because alcohol and these medications together could potentially result in this serious and potentially life-threatening condition.

People taking any of the above medications (or any medications for other conditions) should not adopt a low carb or ketogenic lifestyle on their own without first checking with their doctor.

Another thing that people should never do on their own is adjust the dosage of any of their prescribed medication without first discussing it with their doctor. The consequences of doing so can be very serious, even life-threatening. Medication dosages and timing must be adjusted by a doctor.

Another condition which is less common than DKA but is very serious is Hyperosmolar Hyperglycemia State (HHS).  It is life-threatening and has a much greater death rate than DKA, reaching up to 5-10%. It is most commonly seen in people with Type 2 Diabetes (T2D) that have some illness which results in reduced fluid intake, and them becoming seriously dehydrated. Being sick with an infection is one such situation where it is very important for you to see your doctor if you have T2D, so they can monitor you for HHS. You can read more about HHS here.

If you come to see me to adopt a low carb or ketogenic diet, I will work with you to coordinate dietary and lifestyle changes with your doctor, as they monitor your health and adjust the levels of prescribed medications. In more complex cases, I may ask for written consent to coordinate care with your doctor because depending on those medications, your doctor may need to know in advance what level of carbohydrates you have been advised to eat so that they can monitor your health and make adjustments in your medication dosage.

Your health is important and your diet and the medications need to be coordinated and overseen by your doctor. The potential risks are too great to attempt to do this on your own.

Do you have questions as to how I could work with you and your doctor as they oversee you adopting a low carb lifestyle?  Feel free to drop me a note using the Contact Me form on the tab above.

To your good health!
