A hit can change how much you eat and drink without anyone noticing. Appetite may drop in the hours after an impact, a busy day can push lunch to the evening, and it is easy to get through an afternoon on coffee alone. None of that proves anything about an injury. It does give your record one more useful column, because how you fuel your body can affect how you feel and what you remember later.
This entry is simple. Each day, write down three things: roughly how much fluid you had, what you ate and when, and whether anything felt different from the day before. Use plain words. Two large glasses of water before noon, a sandwich around 2, and a light dinner is enough. You are not counting calories or chasing a target. You are building a timeline that a provider can read in under a minute.
Why food and fluid belong in the record
Symptoms are easy to misread when the basics are off. Feeling foggy, lightheaded, or unusually tired can come from many sources, including skipped meals, a long hot practice, or a poor night of sleep. When you write fuel data beside your symptoms, patterns become easier to see. If you felt dizzy only on the day you skipped breakfast and practiced in the heat, that is a different note than dizziness that appears after you have eaten and drunk normally. Neither note is a diagnosis. Both are facts that help the next conversation go faster.
The log also keeps you from over-reading a single day. People tend to remember the worst moment. A line that says Day 2, three meals, about four glasses of fluid, headache mild by evening keeps the day in proportion and shows whether things are trending better or worse.
What to write each day
Keep the entry short enough that you will actually finish it. A workable template has four lines. The first is fluids, with a rough count and the type, such as water, a sports drink, coffee, or soda. The second is meals, with how many you had, roughly when, and whether you skipped any. The third is appetite, which you can mark as normal, lower than usual, or higher than usual. The fourth is anything else you noticed, including symptoms that seem unrelated to the hit.
If you took any medicine, write down its name, the amount, and the time. Do not treat that line as advice about what to take. It is simply a record that a provider may need when they ask what you have used since the hit.
Keep the record honest
Write the entry at the same time each day if you can, such as before bed. If you forget a day, leave the gap and say so. A gap is information. Do not fill it in later with what you think you probably ate, because a guess written as fact will mislead whoever reads the record.
Dates matter here as much as anywhere in the ledger. Put the calendar date at the top of every entry, and add the number of days since the hit. Day 3 is more useful than a few days ago, because the second phrase drifts with memory and the first does not.
When to get examined
A food and fluid log supports care. It does not replace it. Do not wait to be checked if you notice confusion, repeated vomiting, trouble staying awake, a headache that keeps getting worse, weakness or numbness, unequal pupils, slurred speech, or an inability to keep fluids down. Those signs call for prompt medical attention, including emergency care when they are severe. If you are unsure whether a symptom is serious, a visit within the same week is a reasonable step. Bring the log with you. It can help a provider ask better questions, though only a provider who examines you can say what is going on.
Bring it to the visit
Keep the last week of entries on your phone in a note you can show on screen, or print a copy. Read it once before you go so you can point to the day things changed. If you live in the St. Louis metro and are deciding whether to get examined this week, a short written log often makes the first conversation clearer and gives you something concrete to point to when you describe what happened.
