[45F] With decreased urination and anhidrosis

What might be happening

Based on the symptoms you've described, there are a few serious conditions that could be causing your decreased urination and lack of sweating:

1. Acute Kidney Injury (AKI): This is a sudden episode of kidney failure or kidney damage that happens within a few hours or days. It causes waste products to build up in your blood and makes it hard for your kidneys to keep the right balance of fluid in your body. Given your history of kidney stones, this could be a contributing factor. Typical treatments include hospitalization, intravenous fluids, and medications to manage the underlying cause.

2. Severe Dehydration: Despite drinking a lot of water, your body might not be absorbing it properly, leading to severe dehydration. This can cause your urine to become very concentrated and dark in color. Treatment usually involves rehydration through oral or intravenous fluids.

3. Urinary Tract Obstruction: A blockage in your urinary tract, possibly due to kidney stones, could be preventing urine from passing normally. This can lead to decreased urination and dark-colored urine. Treatment often involves removing the obstruction, which may require medical procedures or surgery.

4. Heat Stroke: Lack of sweating in hot conditions is a serious sign of heat stroke, which is a medical emergency. This condition can cause your body to overheat, leading to organ damage. Immediate cooling and medical attention are crucial.

What you can do

1. Seek Immediate Medical Attention: Given the severity of your symptoms, you should seek immediate medical attention. Go to the nearest emergency room or urgent care center. If you feel light-headed, dizzy, or your symptoms worsen, call 911 or have someone drive you to the hospital immediately.

2. Stay Hydrated: Continue to drink plenty of water, but be aware that this alone may not resolve the issue if your body is not absorbing the fluids properly.

3. Avoid Heat Exposure: Stay in a cool environment and avoid strenuous activities to prevent further dehydration and overheating.

4. Monitor Symptoms: Keep track of any additional symptoms such as pain, swelling, or changes in your condition, and report these to the healthcare provider.
