Dear Wabitte,
Apart from the blood explanation, black stool may also occur when it lingers in the intestines for unusually long periods of time. Also high bilirubin concentrations in bile can contribute to darker stools.
The recurring headaches are most likely due to the constipation issue (slower than normal passage of waste). The resulting backflushing of waste and gas reaches the stomach and leads to burping. There, toxins, bacteria and waste particles combine with mucus and move towards the head to escape through the eyes and other orifices. This can affect vision and eye-performance. Aspirin is a dangerous drug.
It is of the same class as Vioxx which was recalled for increasing risk factors, such as heart attack, stroke, stomach bleeding, kidney failure. Hundreds of thousands of people die each year from using these drugs. Asperin is even more dangerous when taken from time to time than if taken ongoing. Bleeding ulcers are a common side-effect. If a headache occurs, it is better not to suppress it but instead to cleanse the colon (colonic, colema, colosan, oxypowder, etc.) and thereby alleviate the pressure. Suppressing heachaches is a leading cause of chronic disease, such as arthritis and cancers. Continued liver flushing will help clear the drugs from the liver.
I hope you will find this helpful for your mum,
Andreas
