What You Need To Know About Mounjaro

Mounjaro is a prescribed medicine that has an active ingredient called tirzepatide. This is intended for people dealing with Type 2 diabetes and people dealing with chronic weight management. It can be administered at home through self-injected dosages.

This should not be used without any proper consultation with an authorized clinic because it may harm you if you use any dosage that is not suitable for your condition. It is best to look for a certified and reputable clinic that offers injectable prescribed medicine for weight loss to ensure your safety and achieve your goals. People who have used this reported that they notice significant changes as early as after a week of using it. However, you should note that results may vary from one person to another and each result will still depend on the patient’s current medical condition.

 

How Does Mounjaro Works

So the question is, how does it actually work? It works by injecting the Mounjaro in your body then sending a signal that is responsible for food control in your body. Naturally, your body has 2 hormones, GLP-1 and GIP, that are released every time you eat. The GLP-1 works as the signal which sends a signal to your brain to stop eating and slow down your digestion while the GIP helps in sugar control.

Most people are having a hard time with their weight loss because their brain is constantly sending signals of food even when your body doesn’t need any food. Typically it is called ‘food noise’ This is where Mounjaro enters. It sends a signal to your brain that blocks that food noise.

Think of it as an activator that automatically makes you feel full even if you are only eating a few portions. Mounjaro also slows down the digestion in your body making you feel full for a longer time and not craving for more food. Overall, it helps you eat less while helping you lose weight as well.

 

When Can You Start Noticing Its Results?

Before you learn about its results, you should also know that the starting dosage should be 2.5mg. This is to allow your body to adapt to the lowest dosage and minimize any possible side effects that may occur. You might be able to see visible results after a week of using it. However, it might not be the grand results that you might be expecting. You might first notice the changes in how you crave for more food compared with your usual routine. Aside from the physical results through your weight loss, you might notice how you are now slowing down in food intake and slower digestion every single day.

But also take note that this may vary from one person to another. Some patients take a longer time to notice visible results and some have experienced noticeable results after using it for a week. It is best to consult with your chosen clinic first so you would know the different dosages and which is appropriate for your condition.

 

What Are The Effects That You Might Notice At The Early Stage

During the first 2 weeks of using Mounjaro, you’ll start to notice some effects aside from weight loss. You will experience a significant decrease in your appetite especially if you tend to eat more before using it. You’ll also reduce the idea of having cravings which leads to decrease of food intake. This is because the Mounjaro is sending signals to your brain to stop eating and decrease your desire of craving for more food. Then after this, you’ll then start to notice minimal weight loss, might be around 1 to 2% of weight loss. It is essential that you keep track of your starting weight so you can properly monitor your progress.

 

What To Expect With Your Results Weekly
  • By Week 1 and 2: You’ll notice mild weight loss and your body starts to adapt to it
  • By Week 3 and 4: You’ll notice significant body weight loss of 2 to 4%
  • By Week 5 to Week 8: You can now increase your dosage which eventually leads to 5 to 7% weight loss
  • By Week 9 to Week 16: You can now start to have a maintenance dosage then you’ll start notice 8 to 12% of weight loss
  • By Week 6– to Week 18: You’ll have up to 20 to 22.5% of weight loss in clinical trials
What To Expect on the 3rd Month Onwards

Once you pass the first 1 to 2 months of using Mounjaro, you can now then try adding more dosage which usually starts at 5mg and above. This is where the most significant weight loss usually occurs since Mounjaro is actually designed as a long-term treatment in treating weight loss. This has been proven to provide benefits while using over various months.

Based on studies, Mounjaro is far more effective than any other non-surgical treatments that aid weight loss. But still, it depends on your current condition whether the timeline of results.

 

What Are The Different Factors Affecting Its Effectiveness

There are various factors that may affect the results of Mounjaro in your situation. This is important to know because results may vary from one person to another. Here are some of the factors that may affect the result of your Mounjaro:

  • Starting weight & BMI: Since each individual has their different weight, it is one of the leading factors in achieving the results. People with a higher weight and BMI tend to experience significant results in terms of numbers. It is because the body has more excess weight to lose initially.
  • Dose titration schedule: It is important to know that you should follow a consistent schedule of dosages when you are undergoing Mounjaro. You need to follow the appropriate number of dosages for each week that you are using it. If ever you miss it, you should consult with your doctor on the next steps so you would know how to administer it.
  • Lifestyle: While Mounjaro is proven to be effective in losing weight, it is also important that you practise a healthy lifestyle, regular exercise, and healthy food habits to help speed up the results of your weight loss management.
  • Underlying health conditions and other medication: This could be a factor especially if your existing health condition might really lead you in gaining weight. It is why thorough consultation is very important to have a proper assessment before going through Mounjaro medication.

What Are The Common Insights of People About Mounjaro

The majority of the people from the UK who have experienced using Mounjaro have said that they’ve lost a huge amount of weight loss within 6 to 9 months of using it. They’ve also said that they have now lessened the food noise in their mind which usually happens before undergoing the medication. For most people, it is a life changing experience to have finally lost weight after many years of trying other ways of weight loss management.

 

What Are The Possible Side Effects & How To Manage It

Just like any other treatments, Mounjaro also has side effects that might be experienced by people who want to try it. Note that these side effects are only temporary but if these become no longer tolerable, make sure to get in touch with your doctor so you can have immediate medical attention.

  • Nausea: This is one of the most common side effects of it. This usually occurs during the first few days after using it as your body is still adjusting to the medication. You can avoid this by not eating any greasy and spicy food. You also need to eat smaller portions of food only and don’t wait until you’re full.
  • Constipation: This is because of the slower digestion of food in your body. To avoid this, gradually include more high fibre food in your food intake and drink lots of water to hydrate your body.
  • diarrhoea: This is because of the changes in your body especially in your digestive system. Stick to plain and bland food to reduce the potential of experiencing this.
  • Fatigue: This is because your body is adjusting to the medication. You might take over the counter medicine if you can’t handle fatigue and headache that might come along with it.

 

How Long Should You Wait To See Mounjaro Results?

If you are talking about the initial effect of it, as early as a few hours after injecting it, you might be able to feel that you are already full without eating too much. While in terms of actual weight loss, you might start noticing its effect with your weight after the 1st week of using then gradually increases as the week progresses. The higher the dose you inject in the succeeding weeks, the more you’ll see noticeable results.
