Menstrual phases, meet smart insights
Most women experience 4 distinct menstrual cycle phases. During the follicular and ovulation phase, research suggests estrogen rises, helping improve glucose regulation — aka helps keep it stable.1,2
In the late luteal phase however, hormonal shifts can reduce insulin sensitivity and increase cravings for sugar, salt, and fat. What could happen if your plate is packed with foods high in sugar, you ask? Large fluctuations in glucose, which may leave you feeling tired, foggy, and moody.3,4
Using Lingo, a CGM, can help you gain insight into your own unique glucose response at different phases of your menstrual cycle. With real-time data in the palm of your hands, you can feel empowered to:
- Spot glucose spikes and adjust your meals and activity
- Fine-tune nutrition based on your unique response
- Track progress as you build healthier habits
- Anticipate glucose fluctuations and adjust habits accordingly (like planning for cycle cravings)
