Why Does My Poop Smell Like Metal - A Quick Guide

Why Does My Poop Smell Like Metal – A Quick Guide today for people who have noticed a bad smell (worse than usual) coming from their poop.

Poop is one of those subjects that a lot of people avoid talking about. Well, I don’t. Pooping is a natural process that occurs on a regular basis to all living beings (If it doesn’t occur regularly to you, then you have a problem 😀 )

So, why be ashamed about talking about poop? It’s a normal process. So, today, I will be talking about it.

We don’t want to admit it, but we all do it. No, we don’t mean everybody poops, everybody checks their poop. You go to the restroom, and you check it out afterward. It might sound gross, but this is something we do and for good reason.

Our poop tells us a great deal about our health, although it’s not nice to look at or think about, our bodies tell us more from our poop than we might think. 

Our general health, gut health, and lifestyle, such as smoking can change our bowel habits and even our psychological health can be represented in our poop

So, have you ever noticed that your poop smells like metal, or your diarrhea smells like metal, and have stopped to question what is going on inside you? 

Today, we will tell you just why this is happening.

Why Does My Poop & Farts Smell Like Metal?

The most basic reason why your poop and farts and anything else coming out of your backside might smell like metal is if you are ingesting too many iron-heavy foods. 

Metallic smelling poop usually dictates that you have possibly high numbers of sulfur-producing bacteria in your gut. However, this can also occur if you are taking iron supplements, or even have bleeding in your gut too! 

Which of these is the cause can and will need to be narrowed down depending on other symptoms that come with it.

So, this could explain why your poo smells of iron. Look at your diet and the supplements you are taking.

Why Does My Poop Smell Like Rusty Metal?

Bowel movements can smell like metal for a number of reasons, however, the smell is not the only thing that you should be thinking of, consider the consistency as well. Your poop might smell like rusty metal if you have blood in your stool. 

However, you won’t be able to tell unless you look at it and see if there is blood in your stool. 

Remember, metallic-smelling poop can happen for a wide variety of reasons, and smell alone cannot tell you the cause. 

Why Does My Poop Smell Like Metal During Pregnancy?

When you’re pregnant, nothing will smell like normal. Chances are your vaginal discharge will smell off, as will your poop, and your taste buds will change too. Your body is going through a whole load of changes, so you shouldn’t be surprised. 

If you get smelly poop or gas when you’re pregnant it might be a sign of intolerance, or you may just be sensitive, and what would normally not smell so bad becomes like an aggressive assault on your sinuses. 

This happens because your senses become more sensitive when you’re pregnant. You may become more sensitive to metallic scents, and while your poop may not actually smell that bad, to you, it might smell like a welders factory.

Why Does My Poop Smell Like Metal After Covid?

Why Does My Poop Smell Like Metal After Covid?

Why does my bowel movement smell like metal after covid? Well, are you sure it actually does? The real question is if it is your poop or your sinuses. 

We ask this because many people who have suffered from Covid-19 have found that they are now suffering more long-term side effects of Anosmia and parosmia, which affect your sense of smell. 

You can lose your sense of smell, or instead, everything will just smell absolutely vulgar. This may mean that your food may smell rotted, metallic, or even like the excretions of a skunk. 

Some report their faces smelling like eggs (metallic/ sulfur), or like cat food. 

If you think your poop smells metallic after covid, it is best to see a doctor determine if it’s your poop or if it’s you! 

Why Does My Poop Smell Like Sulfur?

Your bowel movements may start smelling like sulfur if you eat foods that contain a lot of sulfur, this includes dairy products, garlic, and meats. Some vegetables are like this too, such as cabbage, kale and broccoli. 

Eggs are notorious for this. Remember that your poop smelling is not always a reflection of health, sometimes, it is just a reflection of what you have eaten. 

Food like this will make your gut work even harder in order to digest them, it makes your body produce an even more excessive amount of gas, and in turn, this will make your poop smell awful. 

What Does It Mean When Your Poop Smells Like Chemicals?

If your poop smells like chemicals, you may also be concerned. We can understand when it smells like metal, due to iron and sulfur-rich foods, but chemicals? 

Well, one of the main reasons for bad-smelling feces is malabsorption. This is something that happens when your body is not capable of taking in the adequate nutrients from the food you eat. 

This will often happen if you have a disease or an infection which doesn’t allow your intestines to absorb what is needed from the food that you eat. If that’s the case, you need to see a doctor ASAP.

What The Smell Of Your Poop Says About Your Health

What The Smell Of Your Poop Says About Your Health

The smell of our faeces actually comes from the bacteria inside our colon, which is used to help and break down the food that we digest. 

What does this mean? Well, it means that your poop will smell different depending on any changes in your diet. So, if you suddenly find yourself asking why your stool smells like metal, or why does my poop smells like iron, it might just be dietary changes. 

However, if you find that you are asking why does my poop smell metallic, and even when your diet changes, the smell is the same, it might be time for a trip to the doctor. 

If the smell of your poop changes, and it is accompanied by any pains, discomfort or other symptoms, it is always best to consult a doctor first.

A penny smell is usually like copper, this may be a sign of blood in your stool. You should also look out for black and tarry bowel movements alongside this, as it will usually indicate bleeding in your GI tract in some way.

As I mentioned above, you shouldn’t be ashamed to talk about the natural processes of your body. Not looking after yourself and potential illnesses just because you are ashamed, can cost you!
