Mounjaro, also known as tirzepatide, is a medication primarily used to manage type 2 diabetes by helping control blood sugar levels. In addition to managing type 2 diabetes, it can also curb appetite and delay gastric emptying, which allows you to stick to low-calorie diets and lose weight effectively and sustainably. While effective, Mounjaro can sometimes cause fatigue in those who take it. Understanding the reasons behind this tiredness and finding ways to combat it can help you manage your symptoms better.

Possible reasons why Mounjaro makes you feel tired:

• Impact on brain's sleep/wake cycle: Mounjaro may affect the hypothalamus, a part of the brain that regulates sleep and wakefulness. By altering this cycle, the medication can make you feel more tired than usual, especially during the initial stages of treatment as your body adjusts to the new medication.
  
• Low-calorie intake: Tirzepatide can suppress appetite, leading to lower calorie consumption. When you consume fewer calories, your body might not have enough energy to function optimally, resulting in feelings of fatigue. This is particularly significant if your diet lacks the necessary nutrients to support your energy levels.
  
• Blood sugar fluctuations: Managing blood sugar levels is critical for individuals with diabetes, and Mounjaro helps in this regard. However, in some cases, the medication can cause fluctuations in blood sugar levels. Rapid drops in blood sugar can lead to hypoglycemia, a condition characterized by tiredness, dizziness, and confusion.
  
• Dehydration: Mounjaro can cause side effects such as nausea and vomiting, which may lead to dehydration if not managed properly. Dehydration can significantly contribute to feelings of fatigue as your body struggles to perform its normal functions without adequate fluid levels.
  
• Initial adjustment period: When you start taking Mounjaro, your body might need time to adjust. During this adjustment period, you might experience increased tiredness as your system adapts to the medication's changes.

How to remedy tiredness while on Mounjaro:

• Maintain a balanced diet: Eating a well-balanced diet rich in essential nutrients can help combat fatigue. Ensure your meals include a variety of fruits, vegetables, whole grains, lean proteins, and healthy fats. Avoid skipping meals, and aim to eat small, frequent meals throughout the day to keep your energy levels stable.
  
• Stay hydrated: Drink plenty of water throughout the day to stay hydrated. Proper hydration is essential for maintaining energy levels and overall health. If you experience nausea or vomiting, try to consume small sips of water or an electrolyte solution to prevent dehydration.
  
• Get regular exercise: Engaging in regular physical activity can boost your energy levels and reduce feelings of fatigue. Aim for at least 30 minutes of moderate exercise, such as walking or cycling, most days of the week. Exercise can help improve your overall fitness, enhance your mood, and promote better sleep.
  
• Establish a regular sleep schedule: Maintaining a consistent sleep schedule can help regulate your body's sleep/wake cycle. Go to bed and wake up at the same time each day, even on weekends. Create a relaxing bedtime routine, such as reading a book or taking a warm bath, to signal to your body that it’s time to wind down.
  
• Limit caffeine and screen time: While caffeine can provide a temporary energy boost, consuming it later in the day can interfere with your sleep. Try to avoid caffeine after midday. Additionally, limit your screen time before bed, as the blue light from electronic devices can disrupt your sleep patterns.

• Exposure to morning light: Exposure to natural light in the morning can help regulate your circadian rhythm and improve your sleep quality. Spend time outside in the morning, or open your curtains to let in natural light. This practice can help you feel more alert during the day and promote better sleep at night.
  
• Monitor your blood sugar levels: Regularly monitoring your blood sugar levels can help you identify and manage fluctuations that may contribute to fatigue. If necessary, work with your healthcare provider to adjust your treatment plan to maintain stable blood sugar levels.
  
• Consult your healthcare provider: If you continue to experience tiredness while taking Mounjaro, consult your provider. They can assess your symptoms, review your treatment plan, and suggest adjustments or additional interventions to help manage your fatigue.

While Mounjaro can cause tiredness due to its effects on your sleep/wake cycle, appetite, blood sugar levels, and hydration, there are several strategies you can implement to combat this fatigue. If your fatigue persists, don't hesitate to seek guidance from your healthcare provider at Genesis Lifestyle Medicine to ensure you receive the appropriate care and support.
