Your body is constantly sending signals that reflect your internal health. While some changes may seem minor or harmless, they can sometimes indicate underlying health imbalances that require attention. Identifying and addressing these early signs can prevent more serious health issues from developing.

Below are 10 scientifically supported symptoms that may point to a disruption in your body’s balance, along with guidance on when to consult a healthcare professional. All insights are backed by reputable health organizations, including the Centers for Disease Control and Prevention (CDC), Cleveland Clinic, Mayo Clinic, and the National Institutes of Health (NIH).

1. Crawling or Tingling Sensation in the Legs

A persistent crawling or tingling feeling in your legs, especially at night, could be a symptom of Restless Legs Syndrome (RLS). This neurological condition causes an uncontrollable urge to move the legs and is often worsened by inactivity or sleep.

According to the National Institute of Neurological Disorders and Stroke (NINDS), RLS may be linked to iron deficiency, pregnancy, or chronic conditions like kidney disease.

2. Thickened Skin

Skin thickening may occur due to conditions like eczema, scleroderma, or hormonal imbalances such as hypothyroidism. While sometimes attributed to allergies or chronic inflammation, it’s important to see a dermatologist or endocrinologist if this change appears suddenly or becomes severe.

3. Changes in Handwriting and Loss of Smell

Subtle shifts in handwriting—such as smaller or shakier script—paired with a reduced sense of smell, may be early indicators of Parkinson’s disease, a progressive neurological disorder.

The Parkinson’s Foundation notes that these symptoms often appear years before tremors or movement issues are noticeable.

4. Sudden Aggressive Behavior

Not all mental health issues present as sadness. Irritability, aggression, or mood swings can be signs of depression, anxiety, or other mood disorders. The CDC emphasizes the importance of seeking professional mental health support if behavioral changes interfere with daily life.

5. Excessive Sleeping (Hypersomnia)

Sleeping too much—beyond the recommended 7–9 hours per night—could indicate hypersomnia, which is sometimes associated with autoimmune diseases, thyroid disorders, or chronic fatigue syndrome.

Persistent daytime drowsiness, even after adequate sleep, should be evaluated by a sleep specialist or primary care physician.

6. White or Grey Ring Around the Cornea

A white or grey arc (arcus senilis) around the cornea may be harmless in older adults, but in individuals under 45, it can signal elevated cholesterol levels, which increase the risk of cardiovascular disease.

Routine blood tests can determine lipid levels and help guide dietary or medical interventions.

7. Intense Craving for Salty Foods

Regular cravings for salty foods could reflect more than just taste preference. It may indicate iron deficiency anemia, adrenal insufficiency, dehydration, or premenstrual syndrome (PMS).

The National Institutes of Health (NIH) suggests that bloodwork and a nutritional review are often needed to identify the root cause.

8. Persistent Fatigue and Low Libido

Low energy combined with reduced sexual desire may point to a thyroid imbalance, particularly hypothyroidism, where the body produces insufficient thyroid hormone.

Other symptoms may include weight gain, dry skin, cold sensitivity, and depression. Thyroid function tests (TSH, T3, and T4) can diagnose this condition, which is manageable with medication.

9. Constant Thirst

Feeling unusually thirsty all the time, even without eating salty foods or exercising, could indicate a medical issue like diabetes mellitus, where elevated blood sugar causes dehydration.

Excessive thirst (polydipsia) is also common in conditions like diabetes insipidus, which affects the kidneys’ ability to conserve water. A blood glucose test is essential to rule out diabetes.

10. Frequent Urge to Chew Ice

Regularly chewing ice (pagophagia) is commonly linked to iron deficiency anemia. While the exact cause of this behavior isn’t fully understood, researchers believe that chewing ice may increase alertness in people with low iron levels.

If this behavior becomes a habit, it’s wise to have a complete blood count (CBC) test to assess for anemia.

Why Recognizing These Signs Matters

Health experts agree that early detection is key to preventing and managing chronic diseases. Often, your body gives subtle hints long before a full-blown illness develops. Paying attention to these signs and seeking medical evaluation can lead to timely treatment and improved quality of life.

When symptoms are persistent, worsen over time, or interfere with daily functioning, they should not be ignored. Even something that seems small—like a craving or fatigue—could be a warning sign of a more significant issue.

When to Seek Medical Attention

• Symptoms last for more than a few days or weeks
• Interfere with work, sleep, or daily routines
• Are accompanied by pain, weight changes, or neurological issues
• Change suddenly or worsen over time

A comprehensive exam, along with laboratory and diagnostic tests, can help identify whether a symptom is isolated or part of a broader health condition.

Conclusion: Listen to Your Body

Your body is constantly communicating with you—through energy levels, cravings, sensations, and behavior. By tuning in to these signals and consulting healthcare professionals when necessary, you can maintain better health and prevent complications.

While not all symptoms are serious, ignoring persistent or unexplained changes may delay diagnosis and treatment. Taking a proactive approach to health begins with awareness.
