Uses Of JANUMET 50/500MG TABLET

• Manages type II diabetes mellitus

Benefits of JANUMET 50/500MG TABLET

1. Dual Action for Blood Sugar Control – Combines Sitagliptin (DPP-4 inhibitor) and Metformin (biguanide) to effectively lower high blood sugar levels in type 2 diabetes.
2. Improves Insulin Sensitivity – Helps the body use insulin more efficiently, reducing insulin resistance and promoting better glucose uptake.
3. Reduces Liver Glucose Production – Metformin decreases excess glucose production in the liver, preventing blood sugar spikes.
4. Supports Post-Meal Glucose Control – Sitagliptin enhances incretin hormones, leading to better insulin release and lower post-meal sugar levels.
5. Weight-Neutral & Low Risk of Hypoglycemia – Unlike some diabetes medications, JANUMET 50/500MG TABLET does not cause significant weight gain and has a lower risk of low blood sugar when used correctly.

Who Should Take JANUMET 50/500MG TABLET:

• Adults with type 2 diabetes mellitus who struggle to maintain healthy blood sugar levels despite diet and exercise.
• For patients needing a combination therapy to enhance insulin function and reduce glucose production.
• However, it is not suitable for type 1 diabetes or patients with severe kidney disease. 

How JANUMET 50/500MG TABLET Works

JANUMET 50/500MG TABLET is a combination of Sitagliptin and Metformin, two effective anti-diabetic medications that help control blood sugar levels in type 2 diabetes.

• Metformin, a biguanide, works by reducing glucose production in the liver, improves insulin sensitivity, and decreases sugar absorption in the intestines.
• Sitagliptin, a DPP-4 inhibitor, enhances the body's natural insulin release by preventing the breakdown of incretin hormones, which in turn help lower blood sugar levels after meals.

Together, these diabetes medications provide a dual-action approach to improve glycemic control, making JANUMET 50/500MG TABLET an effective choice for managing type 2 diabetes mellitus.

Diet and Lifestyle Advice

What to Eat and Avoid? – Best Foods to Complement JANUMET 50/500MG TABLET Therapy

A diabetes-friendly diet is essential to maintain stable blood glucose levels and support JANUMET 50/500MG TABLET dual action in controlling blood sugar.

Best Foods for Diabetes (Low-GI and Fiber-Rich Diet):

• Non-starchy vegetables (spinach, broccoli, bell peppers, kale) – High in fiber, low in carbs.
• Whole grains (quinoa, brown rice, oats, whole wheat) – Rich in fiber, promoting slow glucose absorption.
• Lean proteins (chicken, fish, tofu, eggs, legumes) – Helps maintain muscle mass and stabilizes blood sugar.
• Healthy fats (avocados, nuts, seeds, olive oil) – Improves insulin sensitivity and supports heart health.
• Low-GI fruits (berries, apples, oranges, pears) – Provides natural sweetness without blood sugar spikes.
• Probiotic foods (Greek yogurt, kimchi, sauerkraut) – Supports gut health and enhances glucose metabolism.

Foods to Avoid (High-GI and Processed Foods):

• Refined carbohydrates (white bread, pasta, sugary cereals) – Causes rapid blood sugar spikes.
• Sugary foods & beverages (sweets, sodas, fruit juices) – Leads to insulin resistance over time.
• Fried and processed foods (fast food, chips, packaged snacks) – High in unhealthy fats and calories.
• Excessive red and processed meats – May contribute to inflammation and insulin resistance.
• Alcohol in excess – Can interfere with Metformin’s action and lead to low blood sugar episodes (hypoglycemia).

Best Exercises for Diabetes Management:

• Brisk walking (30–45 minutes daily) – Helps lower blood sugar naturally.
• Strength training (2–3 times a week) – Improves muscle mass and insulin response.
• Yoga and stretching – Reduces stress and improves glucose metabolism.
• Cycling or swimming – Low-impact cardio that supports heart health and weight loss.

Maintaining a healthy weight is essential, as excess body fat can lead to insulin resistance. Pairing JANUMET 50/500MG TABLET with regular exercise not only enhances its benefits but also reduces the risk of diabetes complications such as heart disease and nerve damage.

Hydration and Sugar Control – Why Drinking Enough Water Helps Metformin Work Better

Proper hydration is important for diabetes management, especially when taking Metformin-based medications like JANUMET 50/500MG TABLET. Water helps in:

• Flushing excess glucose through urine.
• Enhancing Metformin’s effect by aiding its metabolism.
• Preventing dehydration, which can lead to high blood sugar levels.

How Much Water to Drink?

• Aim for at least 8–10 glasses (2–2.5 liters) per day.
• Increase intake if sweating due to exercise or hot weather.
• Avoid sugary drinks, as they spike blood glucose levels.

By following a balanced diet, regular exercise, and proper hydration, JANUMET 50/500MG TABLET users can significantly improve their blood sugar control and overall diabetes management.
