City of Hope endocrinologist Raynald Samoa, M.D., has seen a lot of people struggle with their weight. His roots are in the South Pacific, a region that has eight of the 10 countries with the highest prevalence of obesity in the world, according to Forbes.com.
Now, as a physician, Samoa is committed to fighting obesity and its associated diseases, including diabetes. Here he offers insight into how certain lifestyle changes can make a dramatic difference in the lives of people with diabetes, whether young or old.
What is an endocrinologist, and who should see one?
An endocrinologist is a specialist who deals with hormonal issues and who is specifically trained to help patients with diabetes, thyroid disorders (including thyroid cancer), osteoporosis and many other hormonally based diseases.
Why is the prevalence of diabetes rising in the United States, particularly among children?
Type 2 diabetes prevalence is rising in the U.S., and many have associated the increase with the rise in obesity. Although the relationship between diabetes and obesity is not a direct one, they do share common causes, such as a high caloric intake and not enough exercise. As processed food has made food more accessible in the U.S., it has also made it easier to increase our caloric intake.
What can one do to prevent diabetes?
To prevent diabetes, one must understand the different types of diabetes:
How is diabetes treated? Are there any new emerging therapies or techniques?
The mainstay for treatment of type 1 diabetes is to replace insulin. This can be done through injections either with a syringe, pen or an insulin pump. Newer studies are looking at the utility of transplanting pancreatic cells into patients with diabetes as a form of treatment, and currently is being studied for patients with low blood-sugar awareness. Type 2 diabetes treatment revolves around making one more sensitive to the effects of insulin and giving more insulin to control blood sugars.
Both types of diabetes require a multidisciplinary team. Treatment plans should include dietary education and follow-up, glucometer use to check blood sugars, identification and treatment of low blood sugars, and medication assessment. With type 2 diabetes, oral medications have been used to both improve insulin resistance and/or provide more insulin to control blood sugars.
Why did you choose this specialty?
I chose this specialty because I am strongly interested in the hormonal pathways that cause these diseases. The epidemic of diabetes that is sweeping across our country motivates me to take the best of science to help patients find the best way for them to live healthier.
