1. Puffy eyes

We've all woken up with puffy eyes after a bad night's sleep or a day of crying. But if the puffiness and bags don't go away with rest or basic care, it could be related to kidney problems or fluid retention. The kidneys are responsible for filtering out toxins, and when they're not working properly, excess fluid can build up in the face, especially around the eyes.

How can you tell if it is serious?

• Does the puffiness not go away during the day?
• Is it accompanied by fatigue, changes in urination, or lower back pain?
• Do you have high blood pressure or circulation problems?

If the answer is yes, see a doctor to rule out kidney or heart problems.

2. Extremely pale skin

If you suddenly notice that your skin looks much paler than normal, it could be a sign of anemia. Iron deficiency anemia reduces the amount of red blood cells in the blood, which affects the oxygenation of the skin, giving it a dull, lifeless tone. It can also be caused by circulatory problems or vitamin B12 deficiency.

How can you tell if you are anemic?

• Do your lips and skin look pale?
• Do you have constant fatigue, dizziness, or shortness of breath?
• Do you have brittle nails or hair loss?

In these cases, it is important to have a blood test to rule out iron and other essential nutrients deficiencies.

3. Yellowish skin and eyes

A yellowish tint to the skin or whites of the eyes may indicate liver problems such as jaundice. This symptom is due to an increase in bilirubin in the blood, which can be caused by hepatitis, gallbladder problems, or even liver damage.

Quick check:

• Do your eyes have a yellowish tint?
• Do you have discomfort on the right side of your belly?
• Have you noticed a change in the color of your urine or stool?
• Do you have frequent nausea or loss of appetite?

If the answer is yes, see your doctor immediately.

4. Sudden appearance of expression lines

Wrinkles can be normal over time, but if they are sudden and deep, they could be a sign of severe dehydration or even an increase in cortisol levels due to chronic stress. Cortisol breaks down the skin's collagen and elastin, accelerating the aging process.

What can you do?

• Drink plenty of water to keep your skin hydrated.
• Manage stress levels with relaxation techniques such as meditation or yoga.
• Eat a diet rich in antioxidants and healthy fatty acids to nourish your skin from the inside out.

5. Dry mouth and chapped lips

Extremely dry and chapped lips can be a sign of dehydration or a deficiency of B vitamins, especially B2 (riboflavin). They can also be a symptom of allergies, hormonal changes, or even diabetes.

Quick check:

• Are you drinking enough water throughout the day?
• Do your lips have sores or cracks at the corners?
• Do you have constant itching or burning?
• If they persist despite good hydration, see a healthcare professional.

6. Extremely oily or dry skin

If you notice a sudden change in the texture of your skin, it could be related to hormonal imbalances. Abnormally oily skin could be a sign of increased androgens, while excessively dry skin could be linked to thyroid problems.

What can you do?

• See if the skin change is accompanied by hair loss, weight change, or extreme fatigue.
• Check your diet and hydration to rule out external causes.

If symptoms persist, see an endocrinologist.

7. Persistent skin rashes or acne in certain areas

While acne is common, certain breakouts may be related to internal problems. For example:

• Acne on the jaw: May be related to hormonal imbalances in women.
• Acne on the cheeks: Usually associated with digestive problems.
• Acne on the T-zone: It may be due to oily skin. One of the causes of this is a diet high in fat and processed products.

8. Excessive facial hair

Excessive facial hair, especially in women, may be a sign of polycystic ovary syndrome (PCOS), a hormonal disorder that affects ovulation and may be related to insulin resistance.

Quick check:

• Do you have hair in areas such as your chin, cheeks, or neck?
• Do you have irregular menstrual cycles or acne?
• Do you have unexplained weight gain?

If the answer is yes, see an endocrinologist.

9. Appearance of new moles or changes in existing moles

If you notice a new mole appearing or any of your moles changing shape, color or size, it may be a sign of melanoma, a type of skin cancer.

For a quick check, follow the ABCDE rule:

• Asymmetry: Is the mole irregularly shaped?
• Borders: Are they irregular or fuzzy?
• Color: Does it have various shades, or has it changed color?
• Diameter: Is it larger than 6 mm?
• Evolution: Has it grown or changed recently?

If you notice any of these signs, see a dermatologist immediately.

10. Melasma (Dark Patches on the Skin)

Melasma is a hyperpigmentation that usually appears on the face, especially in women, due to hormonal changes, sun exposure or the use of contraceptives.

How can it be prevented?

• Use sunscreen daily.
• Avoid prolonged exposure to the sun without protection.
• Consult a dermatologist if spots increase in size or change color.

11. Butterfly Rash

If you notice a reddish, butterfly-shaped rash on your cheeks and the bridge of your nose, it could be a sign of lupus, an autoimmune disease.

Quick check:

• Does the rash appear after exposure to the sun?
• Is it accompanied by fatigue, fever, or joint pain?
• Do you have extreme sensitivity to the sun?

If so, see a doctor to rule out autoimmune diseases.

Bonus: Darkening of the Skin Around the Neck or Armpits

This darkening, called acanthosis nigricans, may be a sign of insulin resistance, a metabolic problem that can lead to type 2 diabetes.

Quick check:

• Does your skin have a thicker texture in these areas?
• Do you have a family history of diabetes?
• Do you suffer from sudden weight gain?

If the answer is yes, get your blood glucose checked.
