Having both breasts augmented means your body carries extra weight at the front of your chest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding the units and how the weight is spread helps you see the full picture of how your body changes.

Having both breasts augmented adds almost 1kg of weight to your chest.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">This extra weight pulls on the skin continuously throughout the day, so the muscles of your upper body carry more load too.<\/p>\n\n\n\n<figure class=\"wp-block-table\"><table class=\"has-fixed-layout\"><thead><tr><th>Implant volume<\/th><th>Weight per side (average)<\/th><th>Total weight for both sides<\/th><th>Everyday comparison<\/th><\/tr><\/thead><tbody><tr><td><strong>300cc<\/strong><\/td><td>300g to 306g<\/td><td>600g to 612g<\/td><td>A small 600ml bottle of drinking water<\/td><\/tr><tr><td><strong>350cc<\/strong><\/td><td>350g to 357g<\/td><td>700g to 714g<\/td><td>A standard-sized tablet with a case<\/td><\/tr><tr><td><strong>400cc<\/strong><\/td><td>400g to 408g<\/td><td>800g to 816g<\/td><td>A medium bottle of drinking water of almost 1 litre<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>How Each Type of Gel Affects How Heavy the Implants Feel<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Every 400cc implant has the same physical weight of about 400g per side.

The muscles of your upper body have to keep pulling against gravity, so you may get <a href=\"https:\/\/s45clinic.com\/en\/symptoms-after-breast-augmentation\/\">back pain after breast augmentation<\/a>. Areas that can be affected include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>the neck and shoulders<\/strong>, which feel pulled as the muscles tense to support your neck<\/li>\n\n\n\n<li><strong>the shoulder blades and upper back<\/strong>, which have to work harder to keep your back straight<\/li>\n\n\n\n<li><strong>the spine at chest level<\/strong>, which takes more pressure, so you may feel tired when you stand or sit at work for long periods<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>A Chance of the Breasts Sagging Sooner Because of the Weight<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Breasts with large implants have a higher chance of <a href=\"https:\/\/s45clinic.com\/en\/breast-sagging\/\">sagging<\/a> sooner than breasts with smaller implants. Carrying almost 1kg gradually stretches the collagen fibres in the skin under the pull of gravity.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Wearing a bra that supports the weight helps keep your shape firm in the long term.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>A Chance of Capsular Contracture and Rippling<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Large implants create high tension inside the breast pocket and increase the chance of physical side effects that need watching. These include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Capsular contracture. <strong>A 400g implant<\/strong> may cause your body to form thick scar tissue around the implant, making the breast hard and tight.<\/li>\n\n\n\n<li>Rippling. <strong>The pressure from the weight of the implant<\/strong> may thin the skin until wave-like ripples appear along the sides of the breast.

Following your doctor&#8217;s advice helps reduce disruption to your daily life, and the result becomes clearer gradually, depending on each person.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Looking after yourself during <a href=\"https:\/\/s45clinic.com\/en\/breast-augmentation-recovery-time\/\">recovery after breast augmentation<\/a> helps the skin around the breasts hold the implants more firmly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Preparing Before Surgery<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Preparing your body to carry 400cc implants helps reduce the load on your muscles after surgery and supports your circulation. Before surgery:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>exercise your core and shoulder-blade muscles<\/strong> in advance, to build the strength to support 800g at your chest<\/li>\n\n\n\n<li><strong>move things you use at home to waist or chest height<\/strong>, to avoid reaching or raising your arms high, which pulls on the implants<\/li>\n\n\n\n<li><strong>stop taking medicines<\/strong> that affect blood clotting, vitamin E and all supplements from 2 weeks before surgery<\/li>\n\n\n\n<li><strong>stop smoking and drinking alcohol<\/strong> 2 to 4 weeks before surgery, to help prevent your blood vessels from narrowing<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Wearing a Support Bra to Carry the Weight<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">A medical bra spreads the pressure and supports the 800g of implant weight in a balanced position. Advice for this stage:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li>Wear a <a href=\"https:\/\/s45clinic.com\/en\/wear-a-bra-after-breast-augmentation\/\">support bra<\/a> 24 hours a day for the first month, to stop the implants from moving down with gravity.<\/li>\n\n\n\n<li>A support bra helps reduce tension on the incision under the breast or in the armpit, which helps the wound heal well.<\/li>\n\n\n\n<li>Sleep on your back with your head raised on a pillow, avoid sleeping on your front, and follow your doctor&#8217;s advice about sleeping on your side.<\/li>\n\n\n\n<li>Avoid lifting anything heavier than 3kg, and avoid exercise that uses your arms for the first 4 weeks.<\/li>\n<\/ul>\n\n\n\n<h2 id=\"\u0e17\u0e33\u0e44\u0e21\u0e04\u0e27\u0e23\u0e40\u0e2a\u0e23\u0e34\u0e21\u0e2b\u0e19\u0e49\u0e32\u0e2d\u0e01\u0e0b\u0e34\u0e25\u0e34\u0e42\u0e04\u0e19-400cc-\u0e17\u0e35\u0e48-s45-clinic\" class=\"wp-block-heading\"><strong>Why Choose S45 Clinic for Breast Augmentation With 400cc Implants?<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">400cc breast augmentation at S45 Clinic starts with a body assessment before surgery, to plan treatment that matches each person&#8217;s body. The clinic focuses on careful planning and does not recommend sizes that go beyond the limits of your body.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">The doctor analyses your body thoroughly to balance what you want with medical limits.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Body Assessment by a Doctor Before Surgery<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Care is provided by doctors who measure the proportions of your chest in detail, including the width of your chest, the thickness of your skin and the strength of your spine.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Assessing your proportions from every angle helps the doctor recommend a suitable surgical technique, such as placing the implant under the muscle, to help spread the pressure and support the 400cc implant so it does not pull on the skin directly.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Operating Room and Follow-Up<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Surgery at S45 Clinic takes place in an operating room under the medical facility&#8217;s cleanliness control system.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">After surgery, the clinic follows up with you regularly, with appointments to check your incision and assess how your skin is recovering, to monitor your recovery in the long term.<\/p>\n\n\n\n<p style=\"border-left: 3px solid #10CFC9; padding-left: 12px;\"><strong>Before choosing a clinic: <\/strong><a href=\"https:\/\/s45clinic.com\/en\/breast-augmentation-where-to-do-s45-clinic\/\">Breast Augmentation in Bangkok, Where to Have It and Why Consider S45 Clinic<\/a><\/p>\n\n\n\n<h2 id=\"\u0e04\u0e33\u0e16\u0e32\u0e21\u0e1e\u0e1a\u0e1a\u0e48\u0e2d\u0e22\u0e40\u0e23\u0e37\u0e48\u0e2d\u0e07\u0e0b\u0e34\u0e25\u0e34\u0e42\u0e04\u0e19-400cc-\u0e19\u0e49\u0e33\u0e2b\u0e19\u0e31\u0e01\u0e40\u0e17\u0e48\u0e32\u0e44\u0e2b\u0e23\u0e48\" class=\"wp-block-heading\"><strong>Frequently Asked Questions About How Much 400cc Implants Weigh<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Questions about how much 400cc implants weigh usually come from concern about the effect on your daily activities and the changes to your body.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Knowing the medical facts in advance helps reduce worry and makes it easier to plan your life after surgery.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Can I Run or Do Strenuous Exercise After 400cc Breast Augmentation?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">Exercise after 400cc breast augmentation needs to be staged according to how your skin recovers, to prevent impact on the 800g of weight. The stages are:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>for the first month<\/strong>, avoid running, jumping or any activity with strong body movement, to reduce tension on the incision<\/li>\n\n\n\n<li><strong>from the second month<\/strong>, you can start light exercise while wearing a high-support sports bra to reduce the movement of your breasts<\/li>\n<\/ul>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>Can I Breastfeed After Having Large Implants?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">In general, breast augmentation through an incision under the breast or in the armpit does not usually affect the milk ducts directly, so most people can still breastfeed. However, some people may produce less milk, so tell your doctor if you plan to become pregnant and talk to them about your own situation.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">A 400cc implant puts more pressure on the milk-producing glands than a smaller implant. Placing the implant under the muscle helps reduce this pressure, so it may help lower the effect on breastfeeding in the future.<\/p>\n\n\n\n<h3 class=\"wp-block-heading\"><strong>If They Feel Too Heavy, Can I Have Them Made Smaller Later?<\/strong><\/h3>\n\n\n\n<p class=\"wp-block-paragraph\">If, after surgery, you feel the weight of 400cc implants disrupts your daily life or you have long-term aches, you can have corrective surgery based on your doctor&#8217;s assessment. Options include:<\/p>\n\n\n\n<ul class=\"wp-block-list\">\n<li><strong>implant exchange surgery<\/strong>, where the existing implants are removed and smaller ones are inserted to suit your body<\/li>\n\n\n\n<li><strong>a breast lift at the same time<\/strong>, used when your existing skin has stretched from the weight, where the doctor reshapes the skin so it looks balanced and firmer<\/li>\n<\/ul>\n\n\n\n<h2 id=\"\u0e2a\u0e23\u0e38\u0e1b\" class=\"wp-block-heading\"><strong>Summary<\/strong><\/h2>\n\n\n\n<p class=\"wp-block-paragraph\">Understanding <strong>how much 400cc implants weigh<\/strong> helps you picture the load of about 800g that your body has to carry. Choosing an <a href=\"https:\/\/s45clinic.com\/en\/breast-augmentation-cc-guide\/\">implant size<\/a> therefore depends mainly on the width of your chest base and your skin thickness, to get a size that fits each person&#8217;s body.<\/p>\n\n\n\n<p class=\"wp-block-paragraph\">Planning surgery together with wearing a support bra consistently helps support the weight and lowers the chance of side effects. Talking to your doctor for a thorough assessment helps you choose a size that suits your proportions.<\/p>\n\n\n\n<div class=\"wp-block-group s45-cta\"><div class=\"wp-block-group__inner-container is-layout-constrained wp-block-group-is-layout-constrained\">\n\n<h3 class=\"wp-block-heading\">Because every body&#8230;<br\/>is different<\/h3>\n\n\n\n<p class=\"s45-cta-lead wp-block-paragraph\">Doctors at S45 Clinic <strong>assess every case before treatment<\/strong> and give advice based on your actual concerns.<\/p>\n\n\n\n<p class=\"s45-cta-slogan wp-block-paragraph\">\u201cReveal the beauty within you\u201d<\/p>\n\n\n\n<div class=\"wp-block-buttons is-layout-flex wp-block-buttons-is-layout-flex\">\n\n<div class=\"wp-block-button s45-cta-line\"><a class=\"wp-block-button__link wp-element-button\" href=\"https:\/\/page.line.me\/s45clinic.official\" target=\"_blank\" rel=\"noreferrer noopener\">Chat with us on LINE<\/a><\/div>\n\n<\/div>\n\n\n\n<p class=\"s45-cta-free wp-block-paragraph\">Message us online<\/p>\n\n\n\n<p class=\"wp-block-paragraph\"><a class=\"s45-cta-tel\" href=\"tel:+6621252543\">Call us +66 2 125 2543<\/a><\/p>\n\n\n\n<div class=\"s45-cta-clinic\"><a class=\"s45-cta-map\" href=\"https:\/\/maps.app.goo.gl\/7cTTtDAiE7NVN4yZA\" target=\"_blank\" rel=\"noreferrer noopener\"><span><strong>S45 Clinic (Sukhumvit 33)<\/strong><em>Open daily 8:30am to 11:30pm.
