Can diabetes-related polyuria cause constipation?
Dr.
Yang: Hello! My husband has been taking medication for hypertension for a long time.
He usually urinates a lot, but recently he has lost weight rapidly and feels extremely thirsty.
After testing his blood sugar two hours after a meal at the clinic, it spiked to 334, and we found out he has diabetes.
He is currently taking Gliclazide MR 30 mg (Diamicron MR 30 mg) and Metformin HCl 500 mg (Glubin F.C.
Tablet).
After taking these medications, he feels very uncomfortable in his stomach and wants to go to the pharmacy to buy something to relieve the discomfort.
Could you please advise? Additionally, my husband has always had a regular bowel movement in the morning, but since starting diabetes medication along with his blood pressure medication, he has become constipated.
Could this be because diabetes patients tend to urinate more, and the blood pressure medication is also a diuretic, leading to constipation? Is it possible to stop the blood pressure medication (as his blood pressure has been normal for the past 1-2 years), or are there ways to improve this situation?

Hello: Diabetes medications may cause gastrointestinal discomfort; sometimes reducing the dosage can help, and other times the body may gradually adapt.
If discomfort persists, it may be necessary to adjust the medication.
Constipation caused by diabetes medications is relatively uncommon.
Blood pressure medications should not be discontinued without medical advice, as most cases require lifelong use and should be managed under a physician's guidance.

More Info
Frequent urination, known medically as polyuria, is a common symptom associated with diabetes, particularly when blood sugar levels are poorly controlled. In your husband's case, the recent diagnosis of diabetes and the high blood sugar reading of 334 mg/dL indicate that his body is struggling to manage glucose levels effectively. This can lead to increased urination as the kidneys work to excrete excess glucose, which pulls water along with it, resulting in more frequent trips to the bathroom.
The relationship between diabetes and gastrointestinal symptoms, such as constipation, is complex. While diabetes itself does not directly cause constipation, the medications used to manage diabetes and other underlying health conditions can influence bowel habits. In your husband's situation, he is taking Gliclazide and Metformin. Metformin, in particular, is known to cause gastrointestinal side effects, including nausea, diarrhea, and sometimes constipation. The discomfort he is experiencing in his stomach may be a side effect of Metformin, and it is essential to discuss these symptoms with his healthcare provider.
Additionally, the use of antihypertensive medications, especially diuretics, can contribute to dehydration, which may lead to constipation. Diuretics increase urine output, which can result in a loss of fluids and electrolytes, potentially causing the stool to become harder and more difficult to pass. If your husband has been experiencing frequent urination due to both diabetes and the diuretic effect of his blood pressure medication, it is plausible that this combination could lead to constipation.
It is crucial not to stop any prescribed medications without consulting a healthcare professional. Abruptly discontinuing blood pressure medication can lead to dangerous fluctuations in blood pressure, which could have serious health implications. Instead, your husband should discuss his symptoms with his doctor, who can evaluate whether a change in medication is necessary or if there are alternative treatments to alleviate his gastrointestinal discomfort.
To manage constipation, several strategies can be employed:
1. Hydration: Ensure adequate fluid intake to help soften the stool.
2. Dietary Fiber: Increase fiber intake through fruits, vegetables, and whole grains, which can promote regular bowel movements.
3. Physical Activity: Encourage regular exercise, which can stimulate bowel function.
4. Medication Review: Discuss with the healthcare provider the possibility of adjusting medications that may contribute to constipation.
In summary, while diabetes-related frequent urination does not directly cause constipation, the interplay of diabetes medications and blood pressure treatments can lead to gastrointestinal issues. It is essential for your husband to work closely with his healthcare team to manage both his diabetes and any side effects from his medications effectively. Regular monitoring of blood sugar levels, adherence to prescribed treatments, and lifestyle modifications can help improve his overall health and well-being.
