But add:

• Several pumps of syrup

• Sugar

• Sweetened cream

• Whipped cream

• Caramel drizzle

and suddenly your “coffee” may contain the energy of a small meal.

That doesn't mean you can never enjoy one.

The issue is frequency.

A dessert-like coffee occasionally is very different from consuming one or two every day without considering the calories or added sugar.

5. Your Teeth Are Developing More Cavities

This is one of the clearest connections between sugar and health.

Bacteria living in dental plaque can metabolize sugars and produce acids.

Those acids attack tooth enamel.

Repeated exposure can contribute to dental caries, commonly known as cavities.

Frequency matters too.

Constantly sipping a sugary drink throughout the day repeatedly exposes your teeth to sugar and acid.

Sticky Sugary Foods Can Be Particularly Problematic

Foods such as:

• Gummies

• Caramels

• Sticky candies

• Sweet dried snacks

can remain in contact with teeth for longer periods.

Sugary acidic drinks create another problem because they may combine sugar exposure with acidity.

Protect Your Teeth

Helpful habits include:

• Brushing with fluoride toothpaste

• Flossing or cleaning between teeth

• Limiting frequent sugary snacks

• Drinking water

• Getting appropriate dental checkups

And remember:

“Natural sugar” can still affect teeth.

Honey, maple syrup, and similar sweeteners aren't magically cavity-proof because they come from natural sources.

6. Your Triglycerides Are Elevated

This sign won't appear in the mirror.

You'll usually discover it through a blood test.

Triglycerides are a type of fat circulating in the blood.

Consuming excess calories—particularly in the context of diets high in refined carbohydrates and added sugars—can contribute to elevated triglycerides.

High triglycerides are associated with cardiovascular and metabolic risk.

Sugary Drinks Can Be Especially Relevant

Regular consumption of sugar-sweetened beverages has been associated with unfavorable metabolic outcomes.

If blood tests repeatedly show elevated triglycerides, your healthcare professional may recommend looking at:

• Added sugar intake

• Refined carbohydrates

• Alcohol consumption

• Body weight

• Physical activity

• Diabetes control

Genetics and certain medications can also affect triglycerides.

So sugar isn't always the only explanation.

7. You’re Experiencing More Acne or Skin Problems

The relationship between diet and acne is more complicated than:

“Sugar causes pimples.”

However, research suggests that high-glycemic dietary patterns may worsen acne in some people.

Foods with a high glycemic load can cause larger glucose and insulin responses, which may influence hormonal and cellular pathways involved in:

• Sebum production

• Inflammation

• Skin-cell growth

Some studies suggest that lower-glycemic diets may improve acne severity in certain individuals.

But Don't Blame Every Breakout on Dessert

Acne can be influenced by:

• Genetics

• Hormones

• Age

• Skin products

• Stress

• Medications

So a breakout after eating chocolate doesn't prove chocolate caused it.

If acne is persistent or severe, a dermatologist can provide evidence-based treatment.

8. You Feel Thirsty and Urinate Frequently

Now we're entering territory that deserves more attention.

Persistent excessive thirst and frequent urination can be symptoms of high blood glucose and diabetes.

When glucose levels become sufficiently elevated, the kidneys may begin excreting excess glucose into urine.

Water follows.

This can lead to increased urination and dehydration, which then causes increased thirst.

Other Possible Diabetes Symptoms Include:

• Fatigue

• Blurred vision

• Slow-healing wounds

• Frequent infections

• Unexplained weight loss

• Increased hunger

However, type 2 diabetes can develop with very few noticeable symptoms.

You cannot diagnose diabetes based on thirst alone.

Blood testing is required.

Does Eating Sugar Directly Cause Diabetes?

The relationship is more complicated.

Eating one sugary dessert does not suddenly cause type 2 diabetes.

Risk is influenced by factors including:

• Genetics

• Age

• Body composition

• Physical activity

• Diet

• Sleep

• Metabolic health

However, regularly consuming excessive calories and sugar-sweetened beverages can contribute to weight gain and metabolic dysfunction, which can increase type 2 diabetes risk.

9. You Have Signs of Fatty Liver or Metabolic Dysfunction

Your liver plays a central role in carbohydrate and fat metabolism.

Consistently consuming excessive calories, particularly alongside obesity and insulin resistance, can contribute to metabolic dysfunction-associated steatotic liver disease (MASLD), previously commonly called nonalcoholic fatty liver disease.

High intake of added sugars—especially sugar-sweetened beverages—can be one part of that picture.

The Problem: Fatty Liver Can Be Silent

Many people with fatty liver have no obvious symptoms.

Some may experience:

• Fatigue

• Mild discomfort in the upper-right abdomen

But these symptoms are nonspecific.

Fatty liver is often discovered through:

• Blood tests

• Ultrasound

• Other imaging

• Medical evaluation for unrelated reasons
