Colorectal cancer is preventable, treatable & beatable! 💙

While March highlights awareness for colorectal cancer, it’s important to encourage others to schedule routine colonoscopies and take proactive steps for their health year-round 🗓️

Routine screenings give doctors the opportunity to identify and remove precancerous polyps before they develop further 🔍

If cancer is already present, surgical intervention can successfully remove affected tissue, giving patients a strong chance at recovery and improved outcomes 💪

We’d love to highlight our incredible Colorectal Surgery team at UMD, Dr. Matthew Schultzel and Dr. Laura DeCesare, dedicated to improving – and often saving – the lives of those affected by colorectal cancer 👏

Your Game Plan to Tackle Diabetes!

Diabetes is a condition that affects your blood sugar levels which may be higher than normal. Sugar is the primary fuel for your cells, and insulin (produced in the pancreas) is the hormone that allows cells to use sugar as energy. Type 1 diabetes mellitus (T1DM), known as insulin-dependent DM, is a condition that occurs because the pancreas will no longer make insulin. In T1DM, taking insulin treatment is necessary to replace what your body can no longer produce. In Type 2 diabetes mellitus (T2DM), your pancreas is still able to make some insulin, but your body is resistant to the insulin and cannot regulate blood sugar normally.

The good news is that there are many ways to increase your body's ability to regulate blood sugar in T2DM, and these include the following:

Dietary changes are your DM game plan's first and most critical components. It is important to reduce your portions of carbohydrates, which turn into sugar. Did you know that when you eat your carbohydrates during your meal is also essential? Studies show that eating the carbohydrate portion of your meal after eating the protein/fat components will cause fewer blood sugar spikes than eating the carbohydrates first.

Lifestyle changes to reduce idle time and increase movement are also very effective for lowering blood sugar. Try to get at least 30 minutes of physical activity five days a week. Physical activity is not limited to exercise at the gym. There are many forms of exercise, such as household chores, yard work, gardening, and even committing to parking at a distance to increase the amount of walking to your destination.

Weight loss! Did you know that some patients can achieve remission of their Diabetes with weight loss? Besides diet and lifestyle changes, there are several classes of diabetic medications that not only help regulate your blood sugar but can also help you lose up to 20% of your weight. These are potential game changers for many people.

Dr. Patricia Park, an Endocrinologist, treats patients with various endocrinology conditions and strongly believes in shared decision-making with her patients. She is particularly interested in incorporating lifestyle medicine to manage metabolic disorders, including Diabetes and Obesity. She sees patients in Murrieta. Schedule an appointment with United Endocrinology Dr. Park to explore treatment options.
