If you don't overeat at Christmas - you're doing it wrong.
Admittedly, when you're seven pigs and blankets and five Yorkshire puddings down, that 'one fart away from a s**t' feeling can be quite unsettling.
To clear the air is Dr Philip Mayhead - consultant gastroenterologist at Benenden Hospital - who has revealed the five most common types of farts and what they say about your health, as reported by The Sun.
1. Foul-smelling farts
That rotten-egg smell we produce is actually due to 'sulphur-containing compounds produced during digestion'.
And Dr Mayhead says that if your eyes water at the same time that's not because It's a Wonderful Life is on.
The gastroenterologist suggests that you lay off the high-sulphur foods, such as cauliflower, broccoli, cabbage and Brussels sprouts, which personally is another excuse to not eat my greens. (Yes I'm 28 and still don't particularly like vegetables).
Dr Mayhead said: "Sometimes, when your farts are really foul-smelling, it is the result of intestinal bacterial colonies producing gases like carbon dioxide, hydrogen and methane."
2. Odourless farts
The silent - but deadly - ninja farts happen because you keep swallowing air while eating or drinking.
These farts usually consist of nitrogen, oxygen, carbon dioxide, and small amounts of other gases, claims the doctor.
3. Excessive flatulence or bloating-related farts
Excessive farting and bloating could be a serious sign that you have irritable bowel syndrome (IBS).
Or it could mean you have lactose intolerance.
Dr Mayhead said: "If you experience frequent, excessive flatulence, it can feel like you need to open your bowels more frequently or have the urgency to go to the toilet.
"For individuals with lactose intolerance, the festive season may bring an additional challenge, as indulging in treats like chocolate can lead to uncomfortable symptoms. Just be mindful."
4. Hot farts
Dr Mayhead explained: "This type of gas occurs as a result of eating foods that are high in capsaicin, such as chillies or spices.
"It might be best to avoid [ingredients] that bring the heat - literally."
5. Normal farts
Dr Mayhead says: "In small quantities, this type of gas is perfectly normal and is just a natural byproduct of digestion.
"When you eat, you swallow air, and your gut bacteria produce gases as they break down food – simple as that."
No matter how you fart, we would like to wish everyone a smelly Christmas and an even smellier New Year.Featured Image Credit: Getty stock images
