Metformin can cause changes in poop, most commonly diarrhea, but also sometimes a dark or black appearance due to sugar excretion, or even light-colored stools (clay-colored), while extended-release (XR) versions can leave behind visible, harmless "ghost tablets". While often normal GI upset, persistent dark, light, or very pale stools, especially with fatigue or jaundice, could signal liver issues and need medical attention, notes the National Institutes of Health (NIH) and the Mayo Clinic.
Because metformin works to control blood sugar in the stomach, imbalances in gut chemicals like serotonin and histamine can potentially lead to diarrhea. Another possible cause of metformin diarrhea has to do with our gut biome. Metformin can alter the bacteria and viruses that naturally exist in our gut.
Generally, Jardiance and metformin are safe to take together. But as with most medications, they can cause their own unique side effects. Common metformin side effects include diarrhea, nausea and vomiting, and gas.

Two signs that metformin is working are that you've seen a reduction in your blood glucose and hemoglobin A1C (your average glucose over the past 2 to 3 months). Nausea and diarrhea are common side effects of metformin, but they usually improve within a few weeks of starting the medication.
It's best to take metformin tablets with, or just after, your evening meal to reduce the chance of getting side effects. Swallow your metformin tablets whole with a drink of water. Do not chew them. If you're taking metformin sachets, pour the powder into a glass and add water (about 150ml).
Avoid high-sugar foods like soda and candy to help metformin work better. Limit processed foods and refined carbs, like white bread and sugary cereals, to maintain blood sugar control. Consuming alcohol with metformin can lead to low blood sugar and serious health issues.
This is normal. The tablet shell may appear whole in the stool. This is not a cause for concern. Make sure you get enough vitamin B12 while you are taking this medication.
Like chronic diarrhea, diabetic diarrhea involves bouts of diarrhea that last for 4 weeks or more, with loose stools occurring more than 3 times a day. Severe diarrhea that is watery, voluminous, and brown in color is also common, as is steatorrhea.
Finding pills in your stool might be normal while taking some medications. But it could be unusual for other drugs, especially if it happens often. If you regularly find ghost pills in your stool, they may be connected to absorption problems from medical conditions, such as IBD.
Metformin is usually the first-line medication for type 2 diabetes because it's effective, affordable, and well-tolerated by most people. Meanwhile, Jardiance may be a better option if you have heart failure, chronic kidney disease, or a high risk of cardiovascular complications.

Below, we'll discuss these five Jardiance interactions, plus foods and drinks you may want to limit.
If you take metformin without food you may end up with an upset stomach, especially if you are just starting treatment. Nausea and vomiting are some of the most common side effects with metformin and can occur in over 30% of patients.
While some studies have reported significant changes in the gut microbiota following metformin treatment, others have found no significant effects [14,15].
Common side effects
Bad poop colors that warrant a doctor visit are primarily black (tarry), red (bloody), and white/pale/clay-colored, as these can signal internal bleeding (upper GI for black, lower for red) or liver/bile duct issues (white/pale). While other colors often come from food (blueberries, beets, green leafy veggies), persistent unusual colors, especially with other symptoms like pain or diarrhea, should be checked by a doctor.
Symptoms of hyperglycaemia
Changes in stool color is not a symptom of diabetes. Your pediatrician will be your best resource in determining if this might represent a problem.

The main sign of metformin working is lower blood sugar levels. You can monitor this by testing your levels regularly and being aware of the symptoms of higher blood sugar. Metformin is working when you notice a reduction in hunger, thirst, and urination frequency. This usually takes about 1 week.

Mixing alcohol with metformin can also put you at risk for lactic acidosis. This is a condition where you have too much lactic acid in your bloodstream and it can cause serious illness. Before you drink alcohol, be sure to talk with a healthcare professional about how to safely enjoy it while on metformin.
In general, you'll want to eat whole foods like fruits, veggies, lean proteins, healthy fats, and whole grains. These foods can promote weight loss, and sticking to them can help you avoid the types of foods that may make side effects worse.
If you have diabetes, too many carbohydrates (carbs), found in sugary and starchy foods can spike your blood sugar. This may make it harder to manage diabetes, and increase your risk of developing complications.
