Many people say their heart sank when they saw on the blood test report that their platelet count had dropped sharply. While going through chemotherapy, it is common for the marrow to tire briefly and for platelets to come down along with it, but staring at that number alone naturally brings worry to the front: "What if the bleeding suddenly won't stop?" Platelets are what clot the blood and stop the bleeding when you get a cut. When they decrease, you bruise easily from small irritations, blood appears from the gums or nose, and bleeding can last longer even from things that were usually nothing. So while the count is low, just changing a few small everyday habits can reduce the risk quite a bit.
The first thing your hand reaches for is brushing your teeth, and being careful starting here helps. Stiff bristles easily scrape the gums and invite bleeding, so switch to soft bristles and brush gently with light pressure. Floss easily digs into the gums, so when the count is very low it is safer to pause it for a while. Shaving is the same. Using an electric razor instead of a blade razor sharply reduces the chance of cuts. Blowing your nose hard or picking it with a finger is a regular cause of nosebleeds, so it is good to consciously do it softly and gently. They may seem like nothing, but these little habits cause more bleeding than you might think.
You also need to pay extra attention to what you eat and to medications. When constipation sets in, you strain in the bathroom, and that can sometimes cause bleeding around the anus. Drinking enough water and eating fiber-rich foods like vegetables and fruit to keep the stool soft is unexpectedly important. And among painkillers, drugs like aspirin or ibuprofen can lower platelet function and worsen bleeding. Before you absently grab whatever was in the medicine cabinet because you have a headache or a fever, I recommend first asking your medical team which painkiller is fine. Some health foods, herbal medicines, and supplements like ginger or ginkgo can also affect bleeding, so if you are taking anything, please tell them honestly.
Setting up an environment that keeps you from getting hurt also brings real peace of mind. Stubbing a foot while walking barefoot or bumping into a corner happens often, so wear socks or slippers even indoors, and do not cut your fingernails and toenails too short. Put off kitchen work that involves handling knives or scissors, sports with hard collisions, and lifting heavy things until your count recovers. A light walk, on the other hand, is actually helpful. If you do bump something and bleeding occurs, do not panic—press that spot firmly with clean gauze for about 10 minutes. In most cases, just applying pressure like this stops it.
Even so, a few signs must not be brushed off. When a nosebleed or gum bleeding will not stop even after pressing for a while, when you vomit blood or see red or black in your stool or urine, when small red spots like dots break out all over your body or bruises multiply even though you were not injured, and when your head suddenly hurts severely, you feel dizzy, or your speech becomes slurred—you must call the hospital right away. These can be dangerous signs such as bleeding inside the head. Asking once and finding out roughly what your usual platelet count is, and from what level you should be careful, makes it much easier to gauge your own condition.
The period when the count is low is mostly temporary, and it often rises again once the marrow recovers, so you need not be too frightened. But if you tend to a few of the habits noted above a little more during that time, you can get through without a major incident. What is written here is only general guidance, so be sure to decide judgments suited to your own count and treatment situation in consultation with your medical team.
