What to Discuss With Your Doctor Before Starting a GLP-1
An open and honest conversation with your doctor is crucial for a successful journey. “Consider why you’re interested in this medication, your goals, and your overall health status,” advises New York endocrinologist and senior medical advisor for Found, Dr. Rekha Kumar. Sahar Berjis, a registered dietitian and founder of Inner Health and Wellness, emphasizes the importance of assessing if your body is ready for this treatment.
Each individual’s experience with GLP-1 medications is unique, depending largely on their medical history. Berjis highlights that existing gut issues like bloating, constipation, nausea, reflux, or irregular bowel habits can complicate the use of GLP-1 medications. Collaborating with your healthcare provider in advance can set you up for long-term success.
Habits to Break Before Starting GLP-1s
Avoid Skipping Meals
GLP-1 medications are designed to slow digestion to control appetite and eating habits. Berjis warns that skipping meals while on these medications can confuse your body. While many people experience reduced cravings, it’s essential to plan regular meals throughout the day to maintain gut health and prevent issues like fatigue, dizziness, and nutrient deficiencies.
Limit High-Fat Foods
Extreme dieting habits, such as consuming very high-fat foods, can hinder the effectiveness of GLP-1 medications. Dr. Kumar emphasizes the importance of balanced nutrition and lifestyle changes alongside medication use. Professional guidance can help mitigate side effects as your body adapts.
Include Essential Food Groups
A well-rounded diet involves adequate portions and nutrient intake. Assessing your protein and fiber intake is crucial before and during your GLP-1 journey, according to Berjis.
Stay Hydrated
Prioritize increasing your water intake to minimize GLP-1 side effects. Berjis points out that dehydration can worsen symptoms like constipation and nausea. Dr. Kumar adds that hydration is essential even after discontinuing the medication to alleviate lingering effects.
Avoid Depending Solely on Medication
View GLP-1 medications as a supportive tool, not a standalone solution for weight loss. Dr. Kumar emphasizes the importance of a sustainable, long-term approach rather than relying on quick fixes. Berjis echoes this sentiment, highlighting the need for holistic support during your weight-loss journey.
Managing GLP-1 Side Effects
The aforementioned habits can exacerbate side effects of GLP-1 medications, underscoring the importance of addressing them proactively. Dr. Kumar stresses the common gastrointestinal issues associated with these medications and the value of guidance from a metabolic health provider to navigate potential changes effectively.
