Why Are My Nipples Itchy? Causes and Simple Solutions

With our tropical climate, humid weather, and hot summers, not to mention overcrowded public transport, we are quite used to the discomfort of sweating and itching. It gets even more aggravating when itching affects areas such as your breasts or nipples. 

It’s even more problematic if the nipple itching is persistent. In addition to the discomfort and awkwardness that comes with nipple itching, there’s also some amount of concern as you can’t help but ask, “Why are my nipples itchy to begin with?” 

Thankfully, there are plenty of simple explanations, and the problem of itchy nipples can be managed effectively with some minor lifestyle changes or home remedies. Of course, addressing it properly requires a clear understanding of itchy nipple causes, so let’s take a closer look at these.

Common reasons your nipples might itch 

In most situations, itchiness of the nipples is not something you should worry about and has unthreatening causes. These include:

1. Hormonal changes: Hormonal changes associated with menstrual cycles cause changes in skin sensitivity and may cause irritation and itching of the nipples.

2. Dryness: During the winter or when exposed to artificial cooling and heating, dryness is a common skin problem that causes chafing and itching on the nipples too.

3. Inflammatory skin conditions: Numerous autoimmune skin conditions, such as eczema and psoriasis, can cause itchy nipples, but this is likely to be accompanied by other symptoms like plaque formation or redness. 

4. Irritants: Exposure to harsh chemicals from a new laundry detergent or bathing soap could also trigger contact dermatitis, which includes symptoms such as itching, redness, and inflammation.  

5. Clothing: Irritation to the breast or nipples can also occur as a result of exposure to certain dyes in clothing or because of friction with the fabric itself.

6. Infections: Moist and warm environments are favourable to the growth of various microbes, particularly fungal or yeast infections, which can also cause nipple itching.

7. Menopause: Reduced oestrogen levels at this stage can increase skin dryness in many women, which also increases the risk of itchy nipples.

8. Pregnancy and breastfeeding: Yes, itchy nipples are another pregnancy symptom, and they are also common in breastfeeding due to irritation in the area.

Nipple itching during pregnancy 

Nipple itching is not one of the commonly listed symptoms of pregnancy, but it’s a fairly common experience for many expectant moms. This is because hormonal changes during pregnancy, including increases in oestrogen and progesterone, are known to affect the skin. In fact, over 90% of all women experience some skin changes during pregnancy, with pruritus or itchy skin being the most common. As the nipples are particularly sensitive, they are also commonly affected. 

In addition to hormonal triggers, itchy nipples during pregnancy can also occur because the skin in the region gets stretched as the breasts grow and nipples expand in preparation for breastfeeding. Although it’s usually harmless, any health changes and pregnancy symptoms should be reported during prenatal visits.

Itchy boobs while breastfeeding 

Soreness and irritation of the nipples are among the most common problems during breastfeeding, as the nipple can get pinched or damaged when babies do not latch correctly. Milk residue and blockage of the milk ducts can also increase breast tenderness and cause nipple itching. 

There is also a higher risk of infections at this time, which can increase nipple itching and irritation. Thrush or candidiasis infection is fairly common and will also produce other symptoms, such as flaking skin. Mastitis is another inflammatory condition that affects the breast tissue, commonly caused by bacteria. In addition to itching, there may also be discharge and pain or burning.

When itching signals something else 

Aside from the common problems that can be easily addressed with small behavioural changes, nipple itching can sometimes indicate the presence of another underlying condition, which must be diagnosed and treated. For example, thyroid disorders, specifically hypothyroidism, can increase breast and nipple itchiness because of skin changes associated with impaired metabolism. Metabolic function is impaired as thyroid hormones play a critical role in regulating metabolism. Other conditions, such as the growth of a tumour, can also cause itching of the nipples, but it’s important to keep in mind that not all tumours are malignant or cancerous, so don’t panic. 

Lastly, nipple itching may also develop as an adverse reaction to certain medications, so if you have recently started any new treatment, discuss these changes with your doctor. 

Soothing the itch at home

In most cases, simple home treatments and lifestyle changes will help:

• You can apply petroleum jelly or natural moisturisers to the nipples, including those containing ingredients such as olive oil, cocoa or shea butter, aloe extract, and mint extract. This is the simplest itchy nipple remedy for quick relief.

• Switch your old bra for one that is well fitted and made from thin cotton fabric to allow for better air flow so that moisture doesn’t remain trapped, and also to reduce friction. Just remember that well-fitted means that it also shouldn’t be too tight.

• Avoid using any soaps, skin lotions, and detergents that contain harsh chemicals. Fragrance-free products with natural ingredients are the best possible choice. 

• Cool gel packs or a simple cool cloth can also be applied to the nipple to relieve soreness and itchiness quickly.

Preventing future discomfort

Although there’s no foolproof way to prevent itchy nipples, there’s a lot that you can do to minimise the risk:

• Always keep the skin in the area well-moisturised with fragrance-free products.

• Try using hypoallergenic skin care and bathing products if your nipple itching is a result of contact dermatitis.

• Use petroleum jelly to minimise friction.

• Avoid long and hot showers as they can strip away natural protective oils from your skin.

• Dab the area gently for drying after a wash, instead of rubbing with a towel.

• When breastfeeding, try to alternate between nipples and allow each side to drain fully before switching.

When to talk to a doctor

In rare circumstances, itchy nipples can be a warning sign of something more serious, like inflammatory breast cancer or Paget’s disease, which is also a type of cancer. However, these types of breast cancers are extremely rare, accounting for under 5% of all breast cancers. Nevertheless, it’s a good idea to be cautious and look out for other symptoms such as lumps in the breast or near the underarms, changes in the shape and size of your breasts or nipples, pain, dimpling, and discharge affecting just one side. If nipple itching occurs along with any of these other symptoms, it’s important that you consult your doctor as soon as possible to get an accurate diagnosis. In most cases, the cause is likely to be benign, but it pays to be proactive and cautious when dealing with such symptoms.
