Here we come with a 7-day diet for constipation. Not only will you find a printable list for this meal plan, but you’ll also find step-by-step recipe guides.
What Should a Diet for Constipation Be Like?
We have prepared a 7-day meal plan for you, but although it is important to eat right to end the constipation phase, it may not be enough.
For this reason, do not forget to drink at least 3 liters of water a day and get active. Water plays a crucial role in making the fiber work better.(1)
Adjusting the sleep pattern well is also very important for the body to perform the digestive process healthily.
Also, even if you solve your constipation problem, never delay it when it’s time to defecate to prevent the next constipation.
