1. Caffeine Withdrawal
The caffeine content in Diet Coke alone can cause problems.
One can of Diet Coke has 47 milligrams of caffeine. This isn't much, but when you drink Diet on the regular, it adds up fast.
Those with caffeine sensitivities may have insomnia, headaches, light-headedness, anxiety, shakiness, or one of many caffeine side effects when they drink too much of this soda.
If you take certain medications, caffeine can even negatively interact with them. Even echinacea, an herb often found in tea and supplements, doesn't mix well with caffeine.
If you're not sensitive to caffeine, you may still run into problems. The more you drink, the more your tolerance to caffeine goes up - and the more addicted you become. This means that to get an energy boost, it will take even more sodas. If you suddenly stop drinking it, you'll go into caffeine withdrawal and start getting headaches.
Although it seems like drinking a beverage should hydrate you, Diet Coke has the opposite effect.
Another one of the Diet Coke side effects is actually dehydration. Caffeine is a diuretic (this means it makes you pee more). This flushes out the water in your body, without effectively replacing it.
Dehydration can make your head hurt and your heart race. Extreme dehydration can actually cause death. Of course, drinking too much Diet Coke probably won't cause extreme hydration, but consistent low-level dehydration can be hard on your body.
3. Brittle Bones
It may surprise you to learn that one of the Diet Coke side effects can be broken bones.
Drinking too much Diet weakens your bones by affecting your calcium levels. Calcium keeps your bones and teeth durable and healthy. However, the phosphate levels in Diet Coke can negatively affect how much calcium your body stores.
When a lot of phosphate is in your bloodstream, it soaks up calcium from your bones. This means that if you fall down, you're much more likely to break a bone. You'll also be at higher risk for osteoporosis later in life, which can come with a whole host of other issues.
4. Fat Storage
Another one of the more surprising Diet Coke side effects is weight gain.
It may seem like a "diet" beverage should have the opposite effect. After all, Diet Coke doesn't contain any carbs, sugar, or calories. However, artificial sweeteners have actually been linked to weight gain, as well as increased levels of diabetes and heart disease.
Researchers aren't quite sure why this happens, but the link has been made clear in multiple studies. It's possible that artificial sweeteners trick your body's metabolism into stories more fat. Other theories suggest that you're prone to consume more sugar and calories from other sources. Either way, diet soda isn't an effective weight loss solution.
5. Aspartame Issues
Diet Coke is sweetened with aspartame, which comes with a host of side effects.
People with certain disorders, such as phenylketonuria, will have to avoid aspartame. But even people without these issues are better off without aspartame.
It can cause everything from headaches to mood swings to digestive issues in otherwise healthy people. If you don't feel well after drinking Diet Coke, aspartame is probably the culprit.
6. Kidney Harm
Drinking a lot of Diet Coke can actually hurt your kidneys.
Kidneys are part of your body's natural detox system. This means that when you consume anything harmful, your kidneys are responsible for flushing it out of your body.
Acidic drinks, like Diet Coke, can be harmful to your kidneys in large amounts, and even lead to kidney stones. Kidney stones are a result of the levels minerals and acid in your urine being unbalanced.
7. High Blood Pressure
Since one of the Diet Coke side effects is weight gain, high blood pressure can often follow.
Diet Coke also contains a lot of sodium, which is another thing that can increase blood pressure levels. In just one can of Diet, there are 57 milligrams of sodium.
You don't have to mix your Diet Coke with rum to get a hangover.
Between the dehydration, aspartame, sodium, and other unhealthy contents and effects of this drink, you can feel terrible the next day after drinking too much.
If you do drink Diet Coke with liquor, that can also make your next-day hangover worse. Due to the dehydration, you're likely to get drunk faster and feel the effects of the alcohol more.
9. Damaged Teeth
Drinking lots of diet soda can harm your teeth, as well as your body.
The interactions with calcium is one issue. However, the acidity of Diet Coke is also linked to poor dental health. Acidity can weaken the enamel of the tooth and cause decay. This can result in more cavities, fillings, and even missing teeth over time.
Added stress levels are linked to the consumption of aspartame. Aspartame can cause mood swings that lead to increased stress and even depression.
Especially if you already have a mood disorder, you'll want to avoid Diet Coke. It can make the effects of the disorder worse. For example, if you have depression and are prone to related fatigue, drinking diet soda can make you feel even more tired.
