Xigduo is an oral medication that combines two active ingredients, dapagliflozin and metformin. Dapagliflozin belongs to a class of medications called sodium-glucose co-transporter-2 (SGLT2) inhibitors, while metformin is a biguanide. Together, they work synergistically to help control blood sugar levels in individuals with type 2 diabetes.

Xigduo works by targeting two different mechanisms involved in blood sugar regulation. Dapagliflozin inhibits the SGLT2 protein in the kidneys, which normally reabsorbs glucose from the urine back into the bloodstream. By inhibiting this protein, dapagliflozin increases urinary glucose excretion, leading to a reduction in blood sugar levels.

Metformin, on the other hand, works primarily by decreasing the production of glucose in the liver and improving insulin sensitivity in the body’s cells. It also helps to reduce the absorption of glucose from the intestines. By combining these two medications, Xigduo provides a dual mechanism of action to effectively manage blood sugar levels.

Xigduo is typically prescribed for individuals diagnosed with type 2 diabetes. It is commonly recommended when lifestyle modifications, such as diet and exercise, are insufficient to control blood sugar levels. Xigduo may be used as a monotherapy or in combination with other antidiabetic medications, depending on the individual’s specific needs.

It is important to note that Xigduo is not approved for use in individuals with type 1 diabetes or diabetic ketoacidosis. Additionally, healthcare professionals consider various factors, such as medical history, kidney function, and concurrent medications, when determining the suitability of Xigduo for a particular patient.

Type 2 Diabetes

Type 2 diabetes is influenced by a combination of genetic and lifestyle factors. While family history and genetics play a significant role, certain lifestyle choices can increase the risk of developing type 2 diabetes. These factors include obesity, sedentary lifestyle, unhealthy diet, high blood pressure, and age.

Type 2 diabetes often develops gradually, and its symptoms may go unnoticed in the early stages. Common signs and symptoms of type 2 diabetes include increased thirst, frequent urination, unexplained weight loss, fatigue, blurred vision, slow-healing sores or infections, and frequent yeast infections.

If left unmanaged, type 2 diabetes can lead to several complications, including heart disease, stroke, kidney disease, nerve damage, foot problems, skin conditions, eye damage, hearing impairment, and Alzheimer’s disease.
