Are you tuned in to what your body is telling you? Subtle changes in your daily habits, energy, or mood could be important health signals. Learn which symptoms to watch for, how to track them, and why your doctor—not the internet—should help you interpret them.
In this article:
- Recognize and track changes in your body's normal patterns, including frequency, triggers, duration, and intensity of symptoms.
- Pay attention to persistent or unusual signs such as changes in bathroom habits, digestive issues, fatigue, headaches, skin and nail changes, mood shifts, and sleep disturbances.
- Keep a symptom diary and consult your healthcare provider for proper evaluation, avoiding self-diagnosis.
Everybody’s an expert on something. It could be the type of work you do or a favorite hobby like gardening, pasta making, or collecting vintage baseball cards. But there’s one expertise only you can claim: knowing your own body. After all, you live there! Your body communicates its needs — things like hunger, thirst, the need to sleep or use the bathroom — and you respond. But not everything your body tells you is that simple and clear. Sometimes, the key message is just that something is “off.” Finding out what is up to you.
Know Your Normal – and Not-Normal
Look for regular patterns in your body and metabolism. Early warning signs, such as disruptions in your sleep or appetite or changes in your bowel habits, can be easy to overlook. As you notice the signals your body is sending you and the changes you’re experiencing, focus on:
- Frequency: How often do you notice this new sign or symptom? Once a week? Daily? Several times a day?
- Triggers: Is there a correlation between your symptoms and a particular food or medication? Do symptoms occur at a certain time of day or with certain behaviors, such as excessive breathlessness after climbing a flight of stairs?
- Duration: How long do your symptoms last? A few minutes? All day?
- Intensity: Note the severity of your symptoms. If it helps, try ranking them in intensity from 1 to 5.
Is Your Body Talking to You?
Every unusual sign or symptom could be an important message about your health. Here are some things to look for:
Changing Bathroom Habits
Everyone experiences occasional constipation or diarrhea, or changes in the consistency, color and frequency of bowel movements. However, it’s worth investigating these changes if they last more than a week or two or if you notice blood in your stool or urine. Other possible concerns include increased urinary urgency, burning with urination, or difficulty emptying your bladder.
Digestive Issues
We all get heartburn now and then, but persistent heartburn could be gastroesophageal reflux disease (GERD). Ongoing nausea or vomiting, difficulty swallowing or persistent abdominal pain should all be discussed with your doctor.
Fatigue
People often confuse fatigue with tiredness. A good night’s sleep is an easy cure for tiredness. Fatigue does not improve with sleep. If you feel constantly exhausted, notice a decrease in your stamina or are having difficulty concentrating, talk to your doctor.
Fingernail Changes
As you will learn in the accompanying article this month on nail health, changes in nail color, thickness or texture are worth investigating. Look for unusual spots or streaks, pitting or horizontal ridges. Fingernail issues can be addressed by a dermatologist.
Headaches
Everyone gets a headache from time to time, but if your headaches become more frequent, it warrants attention. Note any patterns, such as whether the headache is behind the eyes, one-sided or at the base of the skull. Pay attention to whether the headaches occur at a specific time or are accompanied by nausea, vision changes or sensitivity to light and sound.
Lymph Nodes
Changes in your lymph nodes indicate a possible threat to your immune system. Look for swelling under your chin, in your groin or armpits, or behind the ears. Are the nodes tender or painless? Are they one-sided?
Skin Changes
Skin changes that persist for more than a few days should be checked out by your PCP or a dermatologist. Look for rashes, texture changes, slow-healing wounds, discoloration, new moles or changes in existing ones.
Mood
Are you feeling depressed, sad or anxious? Having difficulty concentrating? Unusually short-tempered? Mood changes are not always triggered by life events –- they could have a physiological origin. Notice whether they are accompanied by physical symptoms such as pain and fatigue.
Mouth Symptoms
Pay attention to bleeding gums, persistent sores, white or red patches, color or texture changes in your tongue, persistent dry mouth or jaw pain. Symptoms that interfere with eating or speech are of particular concern.
Sleep Disturbances
Stress, indigestion and arthritis pain are just some of the things that can have an impact on sleep quality. If you have problems falling or staying asleep, snoring and gasping in your sleep or feeling sleepy during the day, discuss them with your doctor.
Weight Changes
Be mindful of significant weight loss or gain without an obvious cause, such as a bout with the stomach flu or overindulging on vacation. Look for any accompanying symptoms such as changes in energy levels or increased hunger or thirst.
Prepare for Your Doctor’s Appointment
When your body talks to you, you should listen. Ignoring symptoms delays diagnosis. On the other hand, paying attention to your symptoms doesn’t qualify you to interpret or treat them. Self-diagnosing can cause you unnecessary stress or, worse, lead you to rationalize away symptoms that shouldn’t be ignored. Dr. Google didn’t go to medical school. Your doctor did.
In preparation for your doctor’s appointment, start a symptom diary tracking your symptoms, possible triggers and when a particular symptom strikes. These are important details that will help your PCP form a picture of your symptoms and general health and help them decide whether you need any diagnostic tests.
