Disadvantages of Coffee

1) Alteration Of Mood And Anxiety 

Caffeine present in coffee has the ability to alter both mood and psychology along with impacting hormones, neurotransmitters function, nerve signalling and muscles. This is highly applicable if you have existing heath conditions like anxiety, heart problems, or diabetes. Avoiding coffee in such cases would improve your health conditions. 

2) Caffeine Addiction

Consuming too much caffeine could result in caffeine overdose, hence leading to a caffeine addiction. This is harmful as it can overstimulate the body, causing headaches,, irritability, lack of concentration, fatigue, digestive problems and change in appetite,  when you don’t get your required caffeine intake. 

3) Pregnancy Risk

     Women who drink large amounts of coffee, could increase the risk of having fertility problems, since caffeine reduces the muscle activities in the Fallopian tubes, which are responsible for the process of delivering the eggs from the ovaries to the womb. According to The British Journal Of Pharmacology,  caffeine could increase complications related to the pregnancy, since it crosses the placenta and reaches the fetus. Caffeine could linger in the fetus’ system, building up to high toxic levels, as the fetus has an immature or developing metabolic system. If the coffee intake increases from 200-300 milligrams per day, a pregnant woman may be subjected to miscarriage, or the delivery of an infant with a low birth wight. 

4) Coffee Used As A Laxative

Peristalsis is a process in the digestive system that urges us to use the bathroom. Coffee simulates this process, hence people tend to use it as a laxative, but this causes an unwanted problem as well. Coffee not only stimulates peristalsis, it also seems to promote gastric emptying. Due to this the food in the stomach is quickly passed into the small intestines, often without being disintegrated or broken down properly, making it difficult for the nutrient from the food to be absorbed. It also increases the chance of inflammation and irritation within the gastrointestinal track. Decaffeinated coffee has the same properties, so no it isn’t an alternative. 

5) Heartburn Problems

Coffee tends to relax in the lower esophageal sphincter causing acid re-flux and heartburn. The esophageal sphincter should stay tightly closed after a meal, preventing the contents of the stomach from coming back to the esophagus, burning its delicate lining with hydrochloric acid. Decaffeinated coffee and other components of coffee also causes heartburn. 

These were a few proven benefits of coffee and few disadvantages, that clearly show the harmful effects of drinking large amounts of coffee. After all everything at a limit is good, when it exceeds the limit it turns harmful.
